Description:
CROSS-REFERENCE TO RELATED APPLICATIONS 
     This application claims priority to U.S. Provisional Patent Application No. 63/156,847, entitled “USER INTERFACE FOR ENROLLING A BIOMETRIC FEATURE,” filed Mar. 4, 2021, the contents of which is hereby incorporated by reference in its entirety. 
    
    
     FIELD 
     The present disclosure relates generally to computer user interfaces, and more specifically to techniques for enrolling a biometric feature for use with a peripheral device. 
     BACKGROUND 
     Electronic devices include a variety of techniques that provide increased security for sensitive information stored on, and/or otherwise accessible via, the electronic devices. For example, electronic devices can require a user to input a password and/or to provide biometric information, such as a fingerprint or an image of the user&#39;s face, before providing access to sensitive information. In addition, electronic devices can require the user to input a password and/or to provide biometric information prior to performing a particular operation, such as completing a transaction. Electronic devices can also be connected to peripheral and/or external devices that provide users with increased flexibility for providing inputs to respective electronic devices. 
     BRIEF SUMMARY 
     Some techniques for enrolling a biometric feature for use with a peripheral device using electronic devices, however, are generally cumbersome and inefficient. For example, some existing techniques use a complex and time-consuming user interface, which may include multiple key presses or keystrokes. Existing techniques require more time than necessary, wasting user time and device energy. This latter consideration is particularly important in battery-operated devices. 
     Accordingly, the present technique provides electronic devices with faster, more efficient methods and interfaces for enrolling a biometric feature for use with a peripheral device. Such methods and interfaces optionally complement or replace other methods for enrolling a biometric feature for use with a peripheral device. Such methods and interfaces reduce the cognitive burden on a user and produce a more efficient human-machine interface. For battery-operated computing devices, such methods and interfaces conserve power and increase the time between battery charges. In addition, such methods and interfaces provide enhanced security by confirming that a user enrolling a biometric feature for use with a peripheral device is in possession of both the peripheral device and the electronic device.

     DESCRIPTION OF EMBODIMENTS 
     The following description sets forth exemplary methods, parameters, and the like. It should be recognized, however, that such description is not intended as a limitation on the scope of the present disclosure but is instead provided as a description of exemplary embodiments. 
     There is a need for electronic devices that provide efficient methods and interfaces for enrolling a biometric feature for use with a peripheral device. For example, there is a need for efficient methods and interfaces for securely enrolling a biometric feature for use with a peripheral that ensure that a user enrolling the biometric feature for use with the peripheral is the same user associated with an electronic device connected to the peripheral. For another example, there is a need for efficient methods and interfaces that reduce an amount of user inputs required to enroll a biometric feature for use with the peripheral, while ensuring that the user enrolling the biometric feature is the same user associated with an electronic device connected to the peripheral. Such techniques can reduce the cognitive burden on a user who enrolls the biometric feature, thereby enhancing productivity. Further, such techniques can reduce processor and battery power otherwise wasted on redundant user inputs. 
     Below,  FIGS.  1 A- 1 B,  2 ,  3 ,  4 A- 4 B, and  5 A- 5 B  provide a description of exemplary devices for performing the techniques for enrolling a biometric feature for use with a peripheral device.  FIGS.  6 A- 6 U  illustrate exemplary user interfaces for enrolling a biometric feature for use with a peripheral device.  FIGS.  7 A- 7 C  are a flow diagram illustrating methods of enrolling a biometric feature for use with a peripheral device in accordance with some embodiments. The user interfaces in  FIGS.  6 A- 6 U  are used to illustrate the processes described below, including the processes in  FIGS.  7 A- 7 C . 
     In addition, in methods described herein where one or more steps are contingent upon one or more conditions having been met, it should be understood that the described method can be repeated in multiple repetitions so that over the course of the repetitions all of the conditions upon which steps in the method are contingent have been met in different repetitions of the method. For example, if a method requires performing a first step if a condition is satisfied, and a second step if the condition is not satisfied, then a person of ordinary skill would appreciate that the claimed steps are repeated until the condition has been both satisfied and not satisfied, in no particular order. Thus, a method described with one or more steps that are contingent upon one or more conditions having been met could be rewritten as a method that is repeated until each of the conditions described in the method has been met. This, however, is not required of system or computer readable medium claims where the system or computer readable medium contains instructions for performing the contingent operations based on the satisfaction of the corresponding one or more conditions and thus is capable of determining whether the contingency has or has not been satisfied without explicitly repeating steps of a method until all of the conditions upon which steps in the method are contingent have been met. A person having ordinary skill in the art would also understand that, similar to a method with contingent steps, a system or computer readable storage medium can repeat the steps of a method as many times as are needed to ensure that all of the contingent steps have been performed. 
     Although the following description uses terms “first,” “second,” etc. to describe various elements, these elements should not be limited by the terms. In some embodiments, these terms are used to distinguish one element from another. For example, a first touch could be termed a second touch, and, similarly, a second touch could be termed a first touch, without departing from the scope of the various described embodiments. In some embodiments, the first touch and the second touch are two separate references to the same touch. In some embodiments, the first touch and the second touch are both touches, but they are not the same touch. 
     The terminology used in the description of the various described embodiments herein is for the purpose of describing particular embodiments only and is not intended to be limiting. As used in the description of the various described embodiments and the appended claims, the singular forms “a,” “an,” and “the” are intended to include the plural forms as well, unless the context clearly indicates otherwise. It will also be understood that the term “and/or” as used herein refers to and encompasses any and all possible combinations of one or more of the associated listed items. It will be further understood that the terms “includes,” “including,” “comprises,” and/or “comprising,” when used in this specification, specify the presence of stated features, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and/or groups thereof. 
     The term “if” is, optionally, construed to mean “when” or “upon” or “in response to determining” or “in response to detecting,” depending on the context. Similarly, the phrase “if it is determined” or “if [a stated condition or event] is detected” is, optionally, construed to mean “upon determining” or “in response to determining” or “upon detecting [the stated condition or event]” or “in response to detecting [the stated condition or event],” depending on the context. 
     Embodiments of electronic devices, user interfaces for such devices, and associated processes for using such devices are described. In some embodiments, the device is a portable communications device, such as a mobile telephone, that also contains other functions, such as PDA and/or music player functions. Exemplary embodiments of portable multifunction devices include, without limitation, the iPhone®, iPod Touch®, and iPad® devices from Apple Inc. of Cupertino, California Other portable electronic devices, such as laptops or tablet computers with touch-sensitive surfaces (e.g., touch screen displays and/or touchpads), are, optionally, used. It should also be understood that, in some embodiments, the device is not a portable communications device, but is a desktop computer with a touch-sensitive surface (e.g., a touch screen display and/or a touchpad). In some embodiments, the electronic device is a computer system that is in communication (e.g., via wireless communication, via wired communication) with a display generation component. The display generation component is configured to provide visual output, such as display via a CRT display, display via an LED display, or display via image projection. In some embodiments, the display generation component is integrated with the computer system. In some embodiments, the display generation component is separate from the computer system. As used herein, “displaying” content includes causing to display the content (e.g., video data rendered or decoded by display controller  156 ) by transmitting, via a wired or wireless connection, data (e.g., image data or video data) to an integrated or external display generation component to visually produce the content. 
     In the discussion that follows, an electronic device that includes a display and a touch-sensitive surface is described. It should be understood, however, that the electronic device optionally includes one or more other physical user-interface devices, such as a physical keyboard, a mouse, and/or a joystick. 
     The device typically supports a variety of applications, such as one or more of the following: a drawing application, a presentation application, a word processing application, a website creation application, a disk authoring application, a spreadsheet application, a gaming application, a telephone application, a video conferencing application, an e-mail application, an instant messaging application, a workout support application, a photo management application, a digital camera application, a digital video camera application, a web browsing application, a digital music player application, and/or a digital video player application. 
     The various applications that are executed on the device optionally use at least one common physical user-interface device, such as the touch-sensitive surface. One or more functions of the touch-sensitive surface as well as corresponding information displayed on the device are, optionally, adjusted and/or varied from one application to the next and/or within a respective application. In this way, a common physical architecture (such as the touch-sensitive surface) of the device optionally supports the variety of applications with user interfaces that are intuitive and transparent to the user. 
     Attention is now directed toward embodiments of portable devices with touch-sensitive displays.  FIG.  1 A  is a block diagram illustrating portable multifunction device  100  with touch-sensitive display system  112  in accordance with some embodiments. Touch-sensitive display  112  is sometimes called a “touch screen” for convenience and is sometimes known as or called a “touch-sensitive display system.” Device  100  includes memory  102  (which optionally includes one or more computer-readable storage mediums), memory controller  122 , one or more processing units (CPUs)  120 , peripherals interface  118 , RF circuitry  108 , audio circuitry  110 , speaker  111 , microphone  113 , input/output (I/O) subsystem  106 , other input control devices  116 , and external port  124 . Device  100  optionally includes one or more optical sensors  164 . Device  100  optionally includes one or more contact intensity sensors  165  for detecting intensity of contacts on device  100  (e.g., a touch-sensitive surface such as touch-sensitive display system  112  of device  100 ). Device  100  optionally includes one or more tactile output generators  167  for generating tactile outputs on device  100  (e.g., generating tactile outputs on a touch-sensitive surface such as touch-sensitive display system  112  of device  100  or touchpad  355  of device  300 ). These components optionally communicate over one or more communication buses or signal lines  103 . 
     As used in the specification and claims, the term “intensity” of a contact on a touch-sensitive surface refers to the force or pressure (force per unit area) of a contact (e.g., a finger contact) on the touch-sensitive surface, or to a substitute (proxy) for the force or pressure of a contact on the touch-sensitive surface. The intensity of a contact has a range of values that includes at least four distinct values and more typically includes hundreds of distinct values (e.g., at least 256). Intensity of a contact is, optionally, determined (or measured) using various approaches and various sensors or combinations of sensors. For example, one or more force sensors underneath or adjacent to the touch-sensitive surface are, optionally, used to measure force at various points on the touch-sensitive surface. In some implementations, force measurements from multiple force sensors are combined (e.g., a weighted average) to determine an estimated force of a contact. Similarly, a pressure-sensitive tip of a stylus is, optionally, used to determine a pressure of the stylus on the touch-sensitive surface. Alternatively, the size of the contact area detected on the touch-sensitive surface and/or changes thereto, the capacitance of the touch-sensitive surface proximate to the contact and/or changes thereto, and/or the resistance of the touch-sensitive surface proximate to the contact and/or changes thereto are, optionally, used as a substitute for the force or pressure of the contact on the touch-sensitive surface. In some implementations, the substitute measurements for contact force or pressure are used directly to determine whether an intensity threshold has been exceeded (e.g., the intensity threshold is described in units corresponding to the substitute measurements). In some implementations, the substitute measurements for contact force or pressure are converted to an estimated force or pressure, and the estimated force or pressure is used to determine whether an intensity threshold has been exceeded (e.g., the intensity threshold is a pressure threshold measured in units of pressure). Using the intensity of a contact as an attribute of a user input allows for user access to additional device functionality that may otherwise not be accessible by the user on a reduced-size device with limited real estate for displaying affordances (e.g., on a touch-sensitive display) and/or receiving user input (e.g., via a touch-sensitive display, a touch-sensitive surface, or a physical/mechanical control such as a knob or a button). 
     As used in the specification and claims, the term “tactile output” refers to physical displacement of a device relative to a previous position of the device, physical displacement of a component (e.g., a touch-sensitive surface) of a device relative to another component (e.g., housing) of the device, or displacement of the component relative to a center of mass of the device that will be detected by a user with the user&#39;s sense of touch. For example, in situations where the device or the component of the device is in contact with a surface of a user that is sensitive to touch (e.g., a finger, palm, or other part of a user&#39;s hand), the tactile output generated by the physical displacement will be interpreted by the user as a tactile sensation corresponding to a perceived change in physical characteristics of the device or the component of the device. For example, movement of a touch-sensitive surface (e.g., a touch-sensitive display or trackpad) is, optionally, interpreted by the user as a “down click” or “up click” of a physical actuator button. In some cases, a user will feel a tactile sensation such as an “down click” or “up click” even when there is no movement of a physical actuator button associated with the touch-sensitive surface that is physically pressed (e.g., displaced) by the user&#39;s movements. As another example, movement of the touch-sensitive surface is, optionally, interpreted or sensed by the user as “roughness” of the touch-sensitive surface, even when there is no change in smoothness of the touch-sensitive surface. While such interpretations of touch by a user will be subject to the individualized sensory perceptions of the user, there are many sensory perceptions of touch that are common to a large majority of users. Thus, when a tactile output is described as corresponding to a particular sensory perception of a user (e.g., an “up click,” a “down click,” “roughness”), unless otherwise stated, the generated tactile output corresponds to physical displacement of the device or a component thereof that will generate the described sensory perception for a typical (or average) user. 
     It should be appreciated that device  100  is only one example of a portable multifunction device, and that device  100  optionally has more or fewer components than shown, optionally combines two or more components, or optionally has a different configuration or arrangement of the components. The various components shown in  FIG.  1 A  are implemented in hardware, software, or a combination of both hardware and software, including one or more signal processing and/or application-specific integrated circuits. 
     Memory  102  optionally includes high-speed random access memory and optionally also includes non-volatile memory, such as one or more magnetic disk storage devices, flash memory devices, or other non-volatile solid-state memory devices. Memory controller  122  optionally controls access to memory  102  by other components of device  100 . 
     Peripherals interface  118  can be used to couple input and output peripherals of the device to CPU  120  and memory  102 . The one or more processors  120  run or execute various software programs (such as computer programs (e.g., including instructions)) and/or sets of instructions stored in memory  102  to perform various functions for device  100  and to process data. In some embodiments, peripherals interface  118 , CPU  120 , and memory controller  122  are, optionally, implemented on a single chip, such as chip  104 . In some other embodiments, they are, optionally, implemented on separate chips. 
     RF (radio frequency) circuitry  108  receives and sends RF signals, also called electromagnetic signals. RF circuitry  108  converts electrical signals to/from electromagnetic signals and communicates with communications networks and other communications devices via the electromagnetic signals. RF circuitry  108  optionally includes well-known circuitry for performing these functions, including but not limited to an antenna system, an RF transceiver, one or more amplifiers, a tuner, one or more oscillators, a digital signal processor, a CODEC chipset, a subscriber identity module (SIM) card, memory, and so forth.

The RF circuitry  108  optionally includes well-known circuitry for detecting near field communication (NFC) fields, such as by a short-range communication radio. The wireless communication optionally uses any of a plurality of communications standards, protocols, and technologies, including but not limited to Global System for Mobile Communications (GSM), Enhanced Data GSM Environment (EDGE), high-speed downlink packet access (HSDPA), high-speed uplink packet access (HSUPA), Evolution, Data-Only (EV-DO), HSPA, HSPA+, Dual-Cell HSPA (DC-HSPDA), long term evolution (LTE), near field communication (NFC), wideband code division multiple access (W-CDMA), code division multiple access (CDMA), time division multiple access (TDMA), Bluetooth, Bluetooth Low Energy (BTLE), Wireless Fidelity (Wi-Fi) (e.g., IEEE 802.11a, IEEE 802.11b, IEEE 802.11g, IEEE 802.11n, and/or IEEE 802.11ac), voice over Internet Protocol (VoIP), Wi-MAX, a protocol for e-mail (e.g., Internet message access protocol (IMAP) and/or post office protocol (POP)), instant messaging (e.g., extensible messaging and presence protocol (XMPP), Session Initiation Protocol for Instant Messaging and Presence Leveraging Extensions (SIMPLE), Instant Messaging and Presence Service (IMPS)), and/or Short Message Service (SMS), or any other suitable communication protocol, including communication protocols not yet developed as of the filing date of this document. 
     Audio circuitry  110 , speaker  111 , and microphone  113  provide an audio interface between a user and device  100 . Audio circuitry  110  receives audio data from peripherals interface  118 , converts the audio data to an electrical signal, and transmits the electrical signal to speaker  111 . Speaker  111  converts the electrical signal to human-audible sound waves. Audio circuitry  110  also receives electrical signals converted by microphone  113  from sound waves. Audio circuitry  110  converts the electrical signal to audio data and transmits the audio data to peripherals interface  118  for processing. Audio data is, optionally, retrieved from and/or transmitted to memory  102  and/or RF circuitry  108  by peripherals interface  118 . In some embodiments, audio circuitry  110  also includes a headset jack (e.g.,  212 ,  FIG.  2   ). The headset jack provides an interface between audio circuitry  110  and removable audio input/output peripherals, such as output-only headphones or a headset with both output (e.g., a headphone for one or both ears) and input (e.g., a microphone). 
     I/O subsystem  106  couples input/output peripherals on device  100 , such as touch screen  112  and other input control devices  116 , to peripherals interface  118 . I/O subsystem  106  optionally includes display controller  156 , optical sensor controller  158 , depth camera controller  169 , intensity sensor controller  159 , haptic feedback controller  161 , and one or more input controllers  160  for other input or control devices. The one or more input controllers  160  receive/send electrical signals from/to other input control devices  116 . The other input control devices  116  optionally include physical buttons (e.g., push buttons, rocker buttons, etc.), dials, slider switches, joysticks, click wheels, and so forth. In some embodiments, input controller(s)  160  are, optionally, coupled to any (or none) of the following: a keyboard, an infrared port, a USB port, and a pointer device such as a mouse. The one or more buttons (e.g.,  208 ,  FIG.  2   ) optionally include an up/down button for volume control of speaker  111  and/or microphone  113 . The one or more buttons optionally include a push button (e.g.,  206 ,  FIG.  2   ). In some embodiments, the electronic device is a computer system that is in communication (e.g., via wireless communication, via wired communication) with one or more input devices. In some embodiments, the one or more input devices include a touch-sensitive surface (e.g., a trackpad, as part of a touch-sensitive display). In some embodiments, the one or more input devices include one or more camera sensors (e.g., one or more optical sensors  164  and/or one or more depth camera sensors  175 ), such as for tracking a user&#39;s gestures (e.g., hand gestures and/or air gestures) as input. In some embodiments, the one or more input devices are integrated with the computer system. In some embodiments, the one or more input devices are separate from the computer system. In some embodiments, an air gesture is a gesture that is detected without the user touching an input element that is part of the device (or independently of an input element that is a part of the device) and is based on detected motion of a portion of the user&#39;s body through the air including motion of the user&#39;s body relative to an absolute reference (e.g., an angle of the user&#39;s arm relative to the ground or a distance of the user&#39;s hand relative to the ground), relative to another portion of the user&#39;s body (e.g., movement of a hand of the user relative to a shoulder of the user, movement of one hand of the user relative to another hand of the user, and/or movement of a finger of the user relative to another finger or portion of a hand of the user), and/or absolute motion of a portion of the user&#39;s body (e.g., a tap gesture that includes movement of a hand in a predetermined pose by a predetermined amount and/or speed, or a shake gesture that includes a predetermined speed or amount of rotation of a portion of the user&#39;s body). 
     A quick press of the push button optionally disengages a lock of touch screen  112  or optionally begins a process that uses gestures on the touch screen to unlock the device, as described in U.S. patent application Ser. No. 11/322,549, “Unlocking a Device by Performing Gestures on an Unlock Image,” filed Dec. 23, 2005, U.S. Pat. No. 7,657,849, which is hereby incorporated by reference in its entirety. A longer press of the push button (e.g.,  206 ) optionally turns power to device  100  on or off. The functionality of one or more of the buttons are, optionally, user-customizable. Touch screen  112  is used to implement virtual or soft buttons and one or more soft keyboards. 
     Touch-sensitive display  112  provides an input interface and an output interface between the device and a user. Display controller  156  receives and/or sends electrical signals from/to touch screen  112 . Touch screen  112  displays visual output to the user. The visual output optionally includes graphics, text, icons, video, and any combination thereof (collectively termed “graphics”). In some embodiments, some or all of the visual output optionally corresponds to user-interface objects. 
     Touch screen  112  has a touch-sensitive surface, sensor, or set of sensors that accepts input from the user based on haptic and/or tactile contact. Touch screen  112  and display controller  156  (along with any associated modules and/or sets of instructions in memory  102 ) detect contact (and any movement or breaking of the contact) on touch screen  112  and convert the detected contact into interaction with user-interface objects (e.g., one or more soft keys, icons, web pages, or images) that are displayed on touch screen  112 . In an exemplary embodiment, a point of contact between touch screen  112  and the user corresponds to a finger of the user. 
     Touch screen  112  optionally uses LCD (liquid crystal display) technology, LPD (light emitting polymer display) technology, or LED (light emitting diode) technology, although other display technologies are used in other embodiments. Touch screen  112  and display controller  156  optionally detect contact and any movement or breaking thereof using any of a plurality of touch sensing technologies now known or later developed, including but not limited to capacitive, resistive, infrared, and surface acoustic wave technologies, as well as other proximity sensor arrays or other elements for determining one or more points of contact with touch screen  112 . In an exemplary embodiment, projected mutual capacitance sensing technology is used, such as that found in the iPhone® and iPod Touch® from Apple Inc. of Cupertino, California 
     A touch-sensitive display in some embodiments of touch screen  112  is, optionally, analogous to the multi-touch sensitive touchpads described in the following U.S. Pat. No. 6,323,846 (Westerman et al.), U.S. Pat. No. 6,570,557 (Westerman et al.), and/or U.S. Pat. No. 6,677,932 (Westerman), and/or U.S. Patent Publication 2002/0015024A1, each of which is hereby incorporated by reference in its entirety. However, touch screen  112  displays visual output from device  100 , whereas touch-sensitive touchpads do not provide visual output.

     Touch screen  112  optionally has a video resolution in excess of 100 dpi. In some embodiments, the touch screen has a video resolution of approximately 160 dpi. The user optionally makes contact with touch screen  112  using any suitable object or appendage, such as a stylus, a finger, and so forth. In some embodiments, the user interface is designed to work primarily with finger-based contacts and gestures, which can be less precise than stylus-based input due to the larger area of contact of a finger on the touch screen. In some embodiments, the device translates the rough finger-based input into a precise pointer/cursor position or command for performing the actions desired by the user. 
     In some embodiments, in addition to the touch screen, device  100  optionally includes a touchpad for activating or deactivating particular functions. In some embodiments, the touchpad is a touch-sensitive area of the device that, unlike the touch screen, does not display visual output. The touchpad is, optionally, a touch-sensitive surface that is separate from touch screen  112  or an extension of the touch-sensitive surface formed by the touch screen. 
     Device  100  also includes power system  162  for powering the various components. Power system  162  optionally includes a power management system, one or more power sources (e.g., battery, alternating current (AC)), a recharging system, a power failure detection circuit, a power converter or inverter, a power status indicator (e.g., a light-emitting diode (LED)) and any other components associated with the generation, management and distribution of power in portable devices. 
     Device  100  optionally also includes one or more optical sensors  164 .  FIG.  1 A  shows an optical sensor coupled to optical sensor controller  158  in I/O subsystem  106 . Optical sensor  164  optionally includes charge-coupled device (CCD) or complementary metal-oxide semiconductor (CMOS) phototransistors. Optical sensor  164  receives light from the environment, projected through one or more lenses, and converts the light to data representing an image. In conjunction with imaging module  143  (also called a camera module), optical sensor  164  optionally captures still images or video. In some embodiments, an optical sensor is located on the back of device  100 , opposite touch screen display  112  on the front of the device so that the touch screen display is enabled for use as a viewfinder for still and/or video image acquisition. In some embodiments, an optical sensor is located on the front of the device so that the user&#39;s image is, optionally, obtained for video conferencing while the user views the other video conference participants on the touch screen display. In some embodiments, the position of optical sensor  164  can be changed by the user (e.g., by rotating the lens and the sensor in the device housing) so that a single optical sensor  164  is used along with the touch screen display for both video conferencing and still and/or video image acquisition. 
     Device  100  optionally also includes one or more depth camera sensors  175 .  FIG.  1 A  shows a depth camera sensor coupled to depth camera controller  169  in I/O subsystem  106 . Depth camera sensor  175  receives data from the environment to create a three dimensional model of an object (e.g., a face) within a scene from a viewpoint (e.g., a depth camera sensor). In some embodiments, in conjunction with imaging module  143  (also called a camera module), depth camera sensor  175  is optionally used to determine a depth map of different portions of an image captured by the imaging module  143 . In some embodiments, a depth camera sensor is located on the front of device  100  so that the user&#39;s image with depth information is, optionally, obtained for video conferencing while the user views the other video conference participants on the touch screen display and to capture selfies with depth map data. In some embodiments, the depth camera sensor  175  is located on the back of device, or on the back and the front of the device  100 . In some embodiments, the position of depth camera sensor  175  can be changed by the user (e.g., by rotating the lens and the sensor in the device housing) so that a depth camera sensor  175  is used along with the touch screen display for both video conferencing and still and/or video image acquisition. 
     In some embodiments, a depth map (e.g., depth map image) contains information (e.g., values) that relates to the distance of objects in a scene from a viewpoint (e.g., a camera, an optical sensor, a depth camera sensor). In one embodiment of a depth map, each depth pixel defines the position in the viewpoint&#39;s Z-axis where its corresponding two-dimensional pixel is located. In some embodiments, a depth map is composed of pixels wherein each pixel is defined by a value (e.g., 0-255). For example, the “0” value represents pixels that are located at the most distant place in a “three dimensional” scene and the “255” value represents pixels that are located closest to a viewpoint (e.g., a camera, an optical sensor, a depth camera sensor) in the “three dimensional” scene. In other embodiments, a depth map represents the distance between an object in a scene and the plane of the viewpoint. In some embodiments, the depth map includes information about the relative depth of various features of an object of interest in view of the depth camera (e.g., the relative depth of eyes, nose, mouth, ears of a user&#39;s face). In some embodiments, the depth map includes information that enables the device to determine contours of the object of interest in a z direction. 
     Device  100  optionally also includes one or more contact intensity sensors  165 .  FIG.  1 A  shows a contact intensity sensor coupled to intensity sensor controller  159  in I/O subsystem  106 . Contact intensity sensor  165  optionally includes one or more piezoresistive strain gauges, capacitive force sensors, electric force sensors, piezoelectric force sensors, optical force sensors, capacitive touch-sensitive surfaces, or other intensity sensors (e.g., sensors used to measure the force (or pressure) of a contact on a touch-sensitive surface). Contact intensity sensor  165  receives contact intensity information (e.g., pressure information or a proxy for pressure information) from the environment. In some embodiments, at least one contact intensity sensor is collocated with, or proximate to, a touch-sensitive surface (e.g., touch-sensitive display system  112 ). In some embodiments, at least one contact intensity sensor is located on the back of device  100 , opposite touch screen display  112 , which is located on the front of device  100 . 
     Device  100  optionally also includes one or more proximity sensors  166 .  FIG.  1 A  shows proximity sensor  166  coupled to peripherals interface  118 . Alternately, proximity sensor  166  is, optionally, coupled to input controller  160  in I/O subsystem  106 . Proximity sensor  166  optionally performs as described in U.S. patent application Ser. No. 11/241,839, “Proximity Detector In Handheld Device”; Ser. No. 11/240,788, “Proximity Detector In Handheld Device”; Ser. No. 11/620,702, “Using Ambient Light Sensor To Augment Proximity Sensor Output”; Ser. No. 11/586,862, “Automated Response To And Sensing Of User Activity In Portable Devices”; and Ser. No. 11/638,251, “Methods And Systems For Automatic Configuration Of Peripherals,” which are hereby incorporated by reference in their entirety.

     Device  100  optionally also includes one or more tactile output generators  167 .  FIG.  1 A  shows a tactile output generator coupled to haptic feedback controller  161  in I/O subsystem  106 . Tactile output generator  167  optionally includes one or more electroacoustic devices such as speakers or other audio components and/or electromechanical devices that convert energy into linear motion such as a motor, solenoid, electroactive polymer, piezoelectric actuator, electrostatic actuator, or other tactile output generating component (e.g., a component that converts electrical signals into tactile outputs on the device). Contact intensity sensor  165  receives tactile feedback generation instructions from haptic feedback module  133  and generates tactile outputs on device  100  that are capable of being sensed by a user of device  100 . In some embodiments, at least one tactile output generator is collocated with, or proximate to, a touch-sensitive surface (e.g., touch-sensitive display system  112 ) and, optionally, generates a tactile output by moving the touch-sensitive surface vertically (e.g., in/out of a surface of device  100 ) or laterally (e.g., back and forth in the same plane as a surface of device  100 ). In some embodiments, at least one tactile output generator sensor is located on the back of device  100 , opposite touch screen display  112 , which is located on the front of device  100 .

In some embodiments, information is displayed on the touch screen display in a portrait view or a landscape view based on an analysis of data received from the one or more accelerometers. Device  100  optionally includes, in addition to accelerometer(s)  168 , a magnetometer and a GPS (or GLONASS or other global navigation system) receiver for obtaining information concerning the location and orientation (e.g., portrait or landscape) of device  100 . 
     In some embodiments, the software components stored in memory  102  include operating system  126 , communication module (or set of instructions)  128 , contact/motion module (or set of instructions)  130 , graphics module (or set of instructions)  132 , text input module (or set of instructions)  134 , Global Positioning System (GPS) module (or set of instructions)  135 , and applications (or sets of instructions)  136 . Furthermore, in some embodiments, memory  102  ( FIG.  1 A ) or  370  ( FIG.  3   ) stores device/global internal state  157 , as shown in  FIGS.  1 A and  3   . Device/global internal state  157  includes one or more of: active application state, indicating which applications, if any, are currently active; display state, indicating what applications, views or other information occupy various regions of touch screen display  112 ; sensor state, including information obtained from the device&#39;s various sensors and input control devices  116 ; and location information concerning the device&#39;s location and/or attitude. 
     Operating system  126  (e.g., Darwin, RTXC, LINUX, UNIX, OS X, iOS, WINDOWS, or an embedded operating system such as VxWorks) includes various software components and/or drivers for controlling and managing general system tasks (e.g., memory management, storage device control, power management, etc.) and facilitates communication between various hardware and software components. 
     Communication module  128  facilitates communication with other devices over one or more external ports  124  and also includes various software components for handling data received by RF circuitry  108  and/or external port  124 . External port  124  (e.g., Universal Serial Bus (USB), FIREWIRE, etc.) is adapted for coupling directly to other devices or indirectly over a network (e.g., the Internet, wireless LAN, etc.). In some embodiments, the external port is a multi-pin (e.g., 30-pin) connector that is the same as, or similar to and/or compatible with, the 30-pin connector used on iPod® (trademark of Apple Inc.) devices. 
     Contact/motion module  130  optionally detects contact with touch screen  112  (in conjunction with display controller  156 ) and other touch-sensitive devices (e.g., a touchpad or physical click wheel). Contact/motion module  130  includes various software components for performing various operations related to detection of contact, such as determining if contact has occurred (e.g., detecting a finger-down event), determining an intensity of the contact (e.g., the force or pressure of the contact or a substitute for the force or pressure of the contact), determining if there is movement of the contact and tracking the movement across the touch-sensitive surface (e.g., detecting one or more finger-dragging events), and determining if the contact has ceased (e.g., detecting a finger-up event or a break in contact). Contact/motion module  130  receives contact data from the touch-sensitive surface. Determining movement of the point of contact, which is represented by a series of contact data, optionally includes determining speed (magnitude), velocity (magnitude and direction), and/or an acceleration (a change in magnitude and/or direction) of the point of contact. These operations are, optionally, applied to single contacts (e.g., one finger contacts) or to multiple simultaneous contacts (e.g., “multitouch”/multiple finger contacts). In some embodiments, contact/motion module  130  and display controller  156  detect contact on a touchpad. 
     In some embodiments, contact/motion module  130  uses a set of one or more intensity thresholds to determine whether an operation has been performed by a user (e.g., to determine whether a user has “clicked” on an icon). In some embodiments, at least a subset of the intensity thresholds are determined in accordance with software parameters (e.g., the intensity thresholds are not determined by the activation thresholds of particular physical actuators and can be adjusted without changing the physical hardware of device  100 ). For example, a mouse “click” threshold of a trackpad or touch screen display can be set to any of a large range of predefined threshold values without changing the trackpad or touch screen display hardware. Additionally, in some implementations, a user of the device is provided with software settings for adjusting one or more of the set of intensity thresholds (e.g., by adjusting individual intensity thresholds and/or by adjusting a plurality of intensity thresholds at once with a system-level click “intensity” parameter). 
     Contact/motion module  130  optionally detects a gesture input by a user. Different gestures on the touch-sensitive surface have different contact patterns (e.g., different motions, timings, and/or intensities of detected contacts). Thus, a gesture is, optionally, detected by detecting a particular contact pattern. For example, detecting a finger tap gesture includes detecting a finger-down event followed by detecting a finger-up (liftoff) event at the same position (or substantially the same position) as the finger-down event (e.g., at the position of an icon). As another example, detecting a finger swipe gesture on the touch-sensitive surface includes detecting a finger-down event followed by detecting one or more finger-dragging events, and subsequently followed by detecting a finger-up (liftoff) event. 
     Graphics module  132  includes various known software components for rendering and displaying graphics on touch screen  112  or other display, including components for changing the visual impact (e.g., brightness, transparency, saturation, contrast, or other visual property) of graphics that are displayed. As used herein, the term “graphics” includes any object that can be displayed to a user, including, without limitation, text, web pages, icons (such as user-interface objects including soft keys), digital images, videos, animations, and the like. 
     In some embodiments, graphics module  132  stores data representing graphics to be used. Each graphic is, optionally, assigned a corresponding code. Graphics module  132  receives, from applications etc., one or more codes specifying graphics to be displayed along with, if necessary, coordinate data and other graphic property data, and then generates screen image data to output to display controller  156 . 
     Haptic feedback module  133  includes various software components for generating instructions used by tactile output generator(s)  167  to produce tactile outputs at one or more locations on device  100  in response to user interactions with device  100 . 
     Text input module  134 , which is, optionally, a component of graphics module  132 , provides soft keyboards for entering text in various applications (e.g., contacts  137 , e-mail  140 , IM  141 , browser  147 , and any other application that needs text input). 
     GPS module  135  determines the location of the device and provides this information for use in various applications (e.g., to telephone  138  for use in location-based dialing; to camera  143  as picture/video metadata; and to applications that provide location-based services such as weather widgets, local yellow page widgets, and map/navigation widgets). 
     Applications  136  optionally include the following modules (or sets of instructions), or a subset or superset thereof:

     Each of the above-identified modules and applications corresponds to a set of executable instructions for performing one or more functions described above and the methods described in this application (e.g., the computer-implemented methods and other information processing methods described herein). These modules (e.g., sets of instructions) need not be implemented as separate software programs (such as computer programs (e.g., including instructions)), procedures, or modules, and thus various subsets of these modules are, optionally, combined or otherwise rearranged in various embodiments. For example, video player module is, optionally, combined with music player module into a single module (e.g., video and music player module  152 ,  FIG.  1 A ). In some embodiments, memory  102  optionally stores a subset of the modules and data structures identified above. Furthermore, memory  102  optionally stores additional modules and data structures not described above. 
     In some embodiments, device  100  is a device where operation of a predefined set of functions on the device is performed exclusively through a touch screen and/or a touchpad. By using a touch screen and/or a touchpad as the primary input control device for operation of device  100 , the number of physical input control devices (such as push buttons, dials, and the like) on device  100  is, optionally, reduced. 
     The predefined set of functions that are performed exclusively through a touch screen and/or a touchpad optionally include navigation between user interfaces. In some embodiments, the touchpad, when touched by the user, navigates device  100  to a main, home, or root menu from any user interface that is displayed on device  100 . In such embodiments, a “menu button” is implemented using a touchpad. In some other embodiments, the menu button is a physical push button or other physical input control device instead of a touchpad. 
       FIG.  1 B  is a block diagram illustrating exemplary components for event handling in accordance with some embodiments. In some embodiments, memory  102  ( FIG.  1 A ) or  370  ( FIG.  3   ) includes event sorter  170  (e.g., in operating system  126 ) and a respective application  136 - 1  (e.g., any of the aforementioned applications  137 - 151 ,  155 ,  380 - 390 ). 
     Event sorter  170  receives event information and determines the application  136 - 1  and application view  191  of application  136 - 1  to which to deliver the event information. Event sorter  170  includes event monitor  171  and event dispatcher module  174 . In some embodiments, application  136 - 1  includes application internal state  192 , which indicates the current application view(s) displayed on touch-sensitive display  112  when the application is active or executing. In some embodiments, device/global internal state  157  is used by event sorter  170  to determine which application(s) is (are) currently active, and application internal state  192  is used by event sorter  170  to determine application views  191  to which to deliver event information. 
     In some embodiments, application internal state  192  includes additional information, such as one or more of: resume information to be used when application  136 - 1  resumes execution, user interface state information that indicates information being displayed or that is ready for display by application  136 - 1 , a state queue for enabling the user to go back to a prior state or view of application  136 - 1 , and a redo/undo queue of previous actions taken by the user. 
     Event monitor  171  receives event information from peripherals interface  118 . Event information includes information about a sub-event (e.g., a user touch on touch-sensitive display  112 , as part of a multi-touch gesture). Peripherals interface  118  transmits information it receives from I/O subsystem  106  or a sensor, such as proximity sensor  166 , accelerometer(s)  168 , and/or microphone  113  (through audio circuitry  110 ). Information that peripherals interface  118  receives from I/O subsystem  106  includes information from touch-sensitive display  112  or a touch-sensitive surface. 
     In some embodiments, event monitor  171  sends requests to the peripherals interface  118  at predetermined intervals. In response, peripherals interface  118  transmits event information. In other embodiments, peripherals interface  118  transmits event information only when there is a significant event (e.g., receiving an input above a predetermined noise threshold and/or for more than a predetermined duration). 
     In some embodiments, event sorter  170  also includes a hit view determination module  172  and/or an active event recognizer determination module  173 . 
     Hit view determination module  172  provides software procedures for determining where a sub-event has taken place within one or more views when touch-sensitive display  112  displays more than one view. Views are made up of controls and other elements that a user can see on the display. 
     Another aspect of the user interface associated with an application is a set of views, sometimes herein called application views or user interface windows, in which information is displayed and touch-based gestures occur. The application views (of a respective application) in which a touch is detected optionally correspond to programmatic levels within a programmatic or view hierarchy of the application. For example, the lowest level view in which a touch is detected is, optionally, called the hit view, and the set of events that are recognized as proper inputs are, optionally, determined based, at least in part, on the hit view of the initial touch that begins a touch-based gesture. 
     Hit view determination module  172  receives information related to sub-events of a touch-based gesture. When an application has multiple views organized in a hierarchy, hit view determination module  172  identifies a hit view as the lowest view in the hierarchy which should handle the sub-event. In most circumstances, the hit view is the lowest level view in which an initiating sub-event occurs (e.g., the first sub-event in the sequence of sub-events that form an event or potential event). Once the hit view is identified by the hit view determination module  172 , the hit view typically receives all sub-events related to the same touch or input source for which it was identified as the hit view. 
     Active event recognizer determination module  173  determines which view or views within a view hierarchy should receive a particular sequence of sub-events. In some embodiments, active event recognizer determination module  173  determines that only the hit view should receive a particular sequence of sub-events. In other embodiments, active event recognizer determination module  173  determines that all views that include the physical location of a sub-event are actively involved views, and therefore determines that all actively involved views should receive a particular sequence of sub-events. In other embodiments, even if touch sub-events were entirely confined to the area associated with one particular view, views higher in the hierarchy would still remain as actively involved views. 
     Event dispatcher module  174  dispatches the event information to an event recognizer (e.g., event recognizer  180 ). In embodiments including active event recognizer determination module  173 , event dispatcher module  174  delivers the event information to an event recognizer determined by active event recognizer determination module  173 . In some embodiments, event dispatcher module  174  stores in an event queue the event information, which is retrieved by a respective event receiver  182 . 
     In some embodiments, operating system  126  includes event sorter  170 . Alternatively, application  136 - 1  includes event sorter  170 . In yet other embodiments, event sorter  170  is a stand-alone module, or a part of another module stored in memory  102 , such as contact/motion module  130 . 
     In some embodiments, application  136 - 1  includes a plurality of event handlers  190  and one or more application views  191 , each of which includes instructions for handling touch events that occur within a respective view of the application&#39;s user interface. Each application view  191  of the application  136 - 1  includes one or more event recognizers  180 . Typically, a respective application view  191  includes a plurality of event recognizers  180 . In other embodiments, one or more of event recognizers  180  are part of a separate module, such as a user interface kit or a higher level object from which application  136 - 1  inherits methods and other properties. In some embodiments, a respective event handler  190  includes one or more of: data updater  176 , object updater  177 , GUI updater  178 , and/or event data  179  received from event sorter  170 . Event handler  190  optionally utilizes or calls data updater  176 , object updater  177 , or GUI updater  178  to update the application internal state  192 . Alternatively, one or more of the application views  191  include one or more respective event handlers  190 . Also, in some embodiments, one or more of data updater  176 , object updater  177 , and GUI updater  178  are included in a respective application view  191 . 
     A respective event recognizer  180  receives event information (e.g., event data  179 ) from event sorter  170  and identifies an event from the event information. Event recognizer  180  includes event receiver  182  and event comparator  184 . In some embodiments, event recognizer  180  also includes at least a subset of: metadata  183 , and event delivery instructions  188  (which optionally include sub-event delivery instructions). 
     Event receiver  182  receives event information from event sorter  170 . The event information includes information about a sub-event, for example, a touch or a touch movement. Depending on the sub-event, the event information also includes additional information, such as location of the sub-event. When the sub-event concerns motion of a touch, the event information optionally also includes speed and direction of the sub-event. In some embodiments, events include rotation of the device from one orientation to another (e.g., from a portrait orientation to a landscape orientation, or vice versa), and the event information includes corresponding information about the current orientation (also called device attitude) of the device. 
     Event comparator  184  compares the event information to predefined event or sub-event definitions and, based on the comparison, determines an event or sub-event, or determines or updates the state of an event or sub-event. In some embodiments, event comparator  184  includes event definitions  186 . Event definitions  186  contain definitions of events (e.g., predefined sequences of sub-events), for example, event 1 ( 187 - 1 ), event 2 ( 187 - 2 ), and others. In some embodiments, sub-events in an event ( 187 ) include, for example, touch begin, touch end, touch movement, touch cancellation, and multiple touching. In one example, the definition for event 1 ( 187 - 1 ) is a double tap on a displayed object. The double tap, for example, comprises a first touch (touch begin) on the displayed object for a predetermined phase, a first liftoff (touch end) for a predetermined phase, a second touch (touch begin) on the displayed object for a predetermined phase, and a second liftoff (touch end) for a predetermined phase. In another example, the definition for event 2 ( 187 - 2 ) is a dragging on a displayed object. The dragging, for example, comprises a touch (or contact) on the displayed object for a predetermined phase, a movement of the touch across touch-sensitive display  112 , and liftoff of the touch (touch end). In some embodiments, the event also includes information for one or more associated event handlers  190 . 
     In some embodiments, event definition  187  includes a definition of an event for a respective user-interface object. In some embodiments, event comparator  184  performs a hit test to determine which user-interface object is associated with a sub-event. For example, in an application view in which three user-interface objects are displayed on touch-sensitive display  112 , when a touch is detected on touch-sensitive display  112 , event comparator  184  performs a hit test to determine which of the three user-interface objects is associated with the touch (sub-event). If each displayed object is associated with a respective event handler  190 , the event comparator uses the result of the hit test to determine which event handler  190  should be activated. For example, event comparator  184  selects an event handler associated with the sub-event and the object triggering the hit test. 
     In some embodiments, the definition for a respective event ( 187 ) also includes delayed actions that delay delivery of the event information until after it has been determined whether the sequence of sub-events does or does not correspond to the event recognizer&#39;s event type. 
     When a respective event recognizer  180  determines that the series of sub-events do not match any of the events in event definitions  186 , the respective event recognizer  180  enters an event impossible, event failed, or event ended state, after which it disregards subsequent sub-events of the touch-based gesture. In this situation, other event recognizers, if any, that remain active for the hit view continue to track and process sub-events of an ongoing touch-based gesture. 
     In some embodiments, a respective event recognizer  180  includes metadata  183  with configurable properties, flags, and/or lists that indicate how the event delivery system should perform sub-event delivery to actively involved event recognizers. In some embodiments, metadata  183  includes configurable properties, flags, and/or lists that indicate how event recognizers interact, or are enabled to interact, with one another. In some embodiments, metadata  183  includes configurable properties, flags, and/or lists that indicate whether sub-events are delivered to varying levels in the view or programmatic hierarchy. 
     In some embodiments, a respective event recognizer  180  activates event handler  190  associated with an event when one or more particular sub-events of an event are recognized. In some embodiments, a respective event recognizer  180  delivers event information associated with the event to event handler  190 . Activating an event handler  190  is distinct from sending (and deferred sending) sub-events to a respective hit view. In some embodiments, event recognizer  180  throws a flag associated with the recognized event, and event handler  190  associated with the flag catches the flag and performs a predefined process. 
     In some embodiments, event delivery instructions  188  include sub-event delivery instructions that deliver event information about a sub-event without activating an event handler. Instead, the sub-event delivery instructions deliver event information to event handlers associated with the series of sub-events or to actively involved views. Event handlers associated with the series of sub-events or with actively involved views receive the event information and perform a predetermined process. 
     In some embodiments, data updater  176  creates and updates data used in application  136 - 1 . For example, data updater  176  updates the telephone number used in contacts module  137 , or stores a video file used in video player module. In some embodiments, object updater  177  creates and updates objects used in application  136 - 1 . For example, object updater  177  creates a new user-interface object or updates the position of a user-interface object. GUI updater  178  updates the GUI. For example, GUI updater  178  prepares display information and sends it to graphics module  132  for display on a touch-sensitive display. 
     In some embodiments, event handler(s)  190  includes or has access to data updater  176 , object updater  177 , and GUI updater  178 . In some embodiments, data updater  176 , object updater  177 , and GUI updater  178  are included in a single module of a respective application  136 - 1  or application view  191 . In other embodiments, they are included in two or more software modules. 
     It shall be understood that the foregoing discussion regarding event handling of user touches on touch-sensitive displays also applies to other forms of user inputs to operate multifunction devices  100  with input devices, not all of which are initiated on touch screens. For example, mouse movement and mouse button presses, optionally coordinated with single or multiple keyboard presses or holds; contact movements such as taps, drags, scrolls, etc. on touchpads; pen stylus inputs; movement of the device; oral instructions; detected eye movements; biometric inputs; and/or any combination thereof are optionally utilized as inputs corresponding to sub-events which define an event to be recognized. 
       FIG.  2    illustrates a portable multifunction device  100  having a touch screen  112  in accordance with some embodiments. The touch screen optionally displays one or more graphics within user interface (UI)  200 . In this embodiment, as well as others described below, a user is enabled to select one or more of the graphics by making a gesture on the graphics, for example, with one or more fingers  202  (not drawn to scale in the figure) or one or more styluses  203  (not drawn to scale in the figure). In some embodiments, selection of one or more graphics occurs when the user breaks contact with the one or more graphics. In some embodiments, the gesture optionally includes one or more taps, one or more swipes (from left to right, right to left, upward and/or downward), and/or a rolling of a finger (from right to left, left to right, upward and/or downward) that has made contact with device  100 . In some implementations or circumstances, inadvertent contact with a graphic does not select the graphic. For example, a swipe gesture that sweeps over an application icon optionally does not select the corresponding application when the gesture corresponding to selection is a tap. 
     Device  100  optionally also include one or more physical buttons, such as “home” or menu button  204 . As described previously, menu button  204  is, optionally, used to navigate to any application  136  in a set of applications that are, optionally, executed on device  100 . Alternatively, in some embodiments, the menu button is implemented as a soft key in a GUI displayed on touch screen  112 . 
     In some embodiments, device  100  includes touch screen  112 , menu button  204 , push button  206  for powering the device on/off and locking the device, volume adjustment button(s)  208 , subscriber identity module (SIM) card slot  210 , headset jack  212 , and docking/charging external port  124 . Push button  206  is, optionally, used to turn the power on/off on the device by depressing the button and holding the button in the depressed state for a predefined time interval; to lock the device by depressing the button and releasing the button before the predefined time interval has elapsed; and/or to unlock the device or initiate an unlock process. In an alternative embodiment, device  100  also accepts verbal input for activation or deactivation of some functions through microphone  113 . Device  100  also, optionally, includes one or more contact intensity sensors  165  for detecting intensity of contacts on touch screen  112  and/or one or more tactile output generators  167  for generating tactile outputs for a user of device  100 . 
       FIG.  3    is a block diagram of an exemplary multifunction device with a display and a touch-sensitive surface in accordance with some embodiments. Device  300  need not be portable. In some embodiments, device  300  is a laptop computer, a desktop computer, a tablet computer, a multimedia player device, a navigation device, an educational device (such as a child&#39;s learning toy), a gaming system, or a control device (e.g., a home or industrial controller). Device  300  typically includes one or more processing units (CPUs)  310 , one or more network or other communications interfaces  360 , memory  370 , and one or more communication buses  320  for interconnecting these components. Communication buses  320  optionally include circuitry (sometimes called a chipset) that interconnects and controls communications between system components. Device  300  includes input/output (I/O) interface  330  comprising display  340 , which is typically a touch screen display. I/O interface  330  also optionally includes a keyboard and/or mouse (or other pointing device)  350  and touchpad  355 , tactile output generator  357  for generating tactile outputs on device  300  (e.g., similar to tactile output generator(s)  167  described above with reference to  FIG.  1 A ), sensors  359  (e.g., optical, acceleration, proximity, touch-sensitive, and/or contact intensity sensors similar to contact intensity sensor(s)  165  described above with reference to  FIG.  1 A ). Memory  370  includes high-speed random access memory, such as DRAM, SRAM, DDR RAM, or other random access solid state memory devices; and optionally includes non-volatile memory, such as one or more magnetic disk storage devices, optical disk storage devices, flash memory devices, or other non-volatile solid state storage devices. Memory  370  optionally includes one or more storage devices remotely located from CPU(s)  310 . In some embodiments, memory  370  stores programs, modules, and data structures analogous to the programs, modules, and data structures stored in memory  102  of portable multifunction device  100  ( FIG.  1 A ), or a subset thereof. Furthermore, memory  370  optionally stores additional programs, modules, and data structures not present in memory  102  of portable multifunction device  100 . For example, memory  370  of device  300  optionally stores drawing module  380 , presentation module  382 , word processing module  384 , website creation module  386 , disk authoring module  388 , and/or spreadsheet module  390 , while memory  102  of portable multifunction device  100  ( FIG.  1 A ) optionally does not store these modules. 
     Each of the above-identified elements in  FIG.  3    is, optionally, stored in one or more of the previously mentioned memory devices. Each of the above-identified modules corresponds to a set of instructions for performing a function described above. The above-identified modules or computer programs (e.g., sets of instructions or including instructions) need not be implemented as separate software programs (such as computer programs (e.g., including instructions)), procedures, or modules, and thus various subsets of these modules are, optionally, combined or otherwise rearranged in various embodiments. In some embodiments, memory  370  optionally stores a subset of the modules and data structures identified above. Furthermore, memory  370  optionally stores additional modules and data structures not described above. 
     Attention is now directed towards embodiments of user interfaces that are, optionally, implemented on, for example, portable multifunction device  100 . 
       FIG.  4 A  illustrates an exemplary user interface for a menu of applications on portable multifunction device  100  in accordance with some embodiments. Similar user interfaces are, optionally, implemented on device  300 . In some embodiments, user interface  400  includes the following elements, or a subset or superset thereof:
         Signal strength indicator(s)  402  for wireless communication(s), such as cellular and Wi-Fi signals;   Time  404 ;   Bluetooth indicator  405 ;   Battery status indicator  406 ;   Tray  408  with icons for frequently used applications, such as:
           Icon  416  for telephone module  138 , labeled “Phone,” which optionally includes an indicator  414  of the number of missed calls or voicemail messages;   Icon  418  for e-mail client module  140 , labeled “Mail,” which optionally includes an indicator  410  of the number of unread e-mails;   Icon  420  for browser module  147 , labeled “Browser;” and   Icon  422  for video and music player module  152 , also referred to as iPod (trademark of Apple Inc.) module  152 , labeled “iPod;” and   
           Icons for other applications, such as:
           Icon  424  for IM module  141 , labeled “Messages;”   Icon  426  for calendar module  148 , labeled “Calendar;”   Icon  428  for image management module  144 , labeled “Photos;”   Icon  430  for camera module  143 , labeled “Camera;”   Icon  432  for online video module  155 , labeled “Online Video;”   Icon  434  for stocks widget  149 - 2 , labeled “Stocks;”   Icon  436  for map module  154 , labeled “Maps;”   Icon  438  for weather widget  149 - 1 , labeled “Weather;”   Icon  440  for alarm clock widget  149 - 4 , labeled “Clock;”   Icon  442  for workout support module  142 , labeled “Workout Support;”   Icon  444  for notes module  153 , labeled “Notes;” and   Icon  446  for a settings application or module, labeled “Settings,” which provides access to settings for device  100  and its various applications  136 .   
               

     It should be noted that the icon labels illustrated in  FIG.  4 A  are merely exemplary. For example, icon  422  for video and music player module  152  is labeled “Music” or “Music Player.” Other labels are, optionally, used for various application icons. In some embodiments, a label for a respective application icon includes a name of an application corresponding to the respective application icon. In some embodiments, a label for a particular application icon is distinct from a name of an application corresponding to the particular application icon. 
       FIG.  4 B  illustrates an exemplary user interface on a device (e.g., device  300 ,  FIG.  3   ) with a touch-sensitive surface  451  (e.g., a tablet or touchpad  355 ,  FIG.  3   ) that is separate from the display  450  (e.g., touch screen display  112 ). Device  300  also, optionally, includes one or more contact intensity sensors (e.g., one or more of sensors  359 ) for detecting intensity of contacts on touch-sensitive surface  451  and/or one or more tactile output generators  357  for generating tactile outputs for a user of device  300 . 
     Although some of the examples that follow will be given with reference to inputs on touch screen display  112  (where the touch-sensitive surface and the display are combined), in some embodiments, the device detects inputs on a touch-sensitive surface that is separate from the display, as shown in  FIG.  4 B . In some embodiments, the touch-sensitive surface (e.g.,  451  in  FIG.  4 B ) has a primary axis (e.g.,  452  in  FIG.  4 B ) that corresponds to a primary axis (e.g.,  453  in  FIG.  4 B ) on the display (e.g.,  450 ). In accordance with these embodiments, the device detects contacts (e.g.,  460  and  462  in  FIG.  4 B ) with the touch-sensitive surface  451  at locations that correspond to respective locations on the display (e.g., in  FIG.  4 B,  460    corresponds to  468  and  462  corresponds to  470 ). In this way, user inputs (e.g., contacts  460  and  462 , and movements thereof) detected by the device on the touch-sensitive surface (e.g.,  451  in  FIG.  4 B ) are used by the device to manipulate the user interface on the display (e.g.,  450  in  FIG.  4 B ) of the multifunction device when the touch-sensitive surface is separate from the display. It should be understood that similar methods are, optionally, used for other user interfaces described herein. 
     Additionally, while the following examples are given primarily with reference to finger inputs (e.g., finger contacts, finger tap gestures, finger swipe gestures), it should be understood that, in some embodiments, one or more of the finger inputs are replaced with input from another input device (e.g., a mouse-based input or stylus input). For example, a swipe gesture is, optionally, replaced with a mouse click (e.g., instead of a contact) followed by movement of the cursor along the path of the swipe (e.g., instead of movement of the contact). As another example, a tap gesture is, optionally, replaced with a mouse click while the cursor is located over the location of the tap gesture (e.g., instead of detection of the contact followed by ceasing to detect the contact). Similarly, when multiple user inputs are simultaneously detected, it should be understood that multiple computer mice are, optionally, used simultaneously, or a mouse and finger contacts are, optionally, used simultaneously. 
       FIG.  5 A  illustrates exemplary personal electronic device  500 . Device  500  includes body  502 . In some embodiments, device  500  can include some or all of the features described with respect to devices  100  and  300  (e.g.,  FIGS.  1 A- 4 B ). In some embodiments, device  500  has touch-sensitive display screen  504 , hereafter touch screen  504 . Alternatively, or in addition to touch screen  504 , device  500  has a display and a touch-sensitive surface. As with devices  100  and  300 , in some embodiments, touch screen  504  (or the touch-sensitive surface) optionally includes one or more intensity sensors for detecting intensity of contacts (e.g., touches) being applied. The one or more intensity sensors of touch screen  504  (or the touch-sensitive surface) can provide output data that represents the intensity of touches. The user interface of device  500  can respond to touches based on their intensity, meaning that touches of different intensities can invoke different user interface operations on device  500 . 
     Exemplary techniques for detecting and processing touch intensity are found, for example, in related applications: International Patent Application Serial No. PCT/US2013/040061, titled “Device, Method, and Graphical User Interface for Displaying User Interface Objects Corresponding to an Application,” filed May 8, 2013, published as WIPO Publication No. WO/2013/169849, and International Patent Application Serial No. PCT/US2013/069483, titled “Device, Method, and Graphical User Interface for Transitioning Between Touch Input to Display Output Relationships,” filed Nov. 11, 2013, published as WIPO Publication No. WO/2014/105276, each of which is hereby incorporated by reference in their entirety. 
     In some embodiments, device  500  has one or more input mechanisms  506  and  508 . Input mechanisms  506  and  508 , if included, can be physical. Examples of physical input mechanisms include push buttons and rotatable mechanisms. In some embodiments, device  500  has one or more attachment mechanisms. Such attachment mechanisms, if included, can permit attachment of device  500  with, for example, hats, eyewear, earrings, necklaces, shirts, jackets, bracelets, watch straps, chains, trousers, belts, shoes, purses, backpacks, and so forth. These attachment mechanisms permit device  500  to be worn by a user. 
       FIG.  5 B  depicts exemplary personal electronic device  500 . In some embodiments, device  500  can include some or all of the components described with respect to  FIGS.  1 A,  1 B , and  3 . Device  500  has bus  512  that operatively couples I/O section  514  with one or more computer processors  516  and memory  518 . I/O section  514  can be connected to display  504 , which can have touch-sensitive component  522  and, optionally, intensity sensor  524  (e.g., contact intensity sensor). In addition, I/O section  514  can be connected with communication unit  530  for receiving application and operating system data, using Wi-Fi, Bluetooth, near field communication (NFC), cellular, and/or other wireless communication techniques. Device  500  can include input mechanisms  506  and/or  508 . Input mechanism  506  is, optionally, a rotatable input device or a depressible and rotatable input device, for example. Input mechanism  508  is, optionally, a button, in some examples. 
     Input mechanism  508  is, optionally, a microphone, in some examples. Personal electronic device  500  optionally includes various sensors, such as GPS sensor  532 , accelerometer  534 , directional sensor  540  (e.g., compass), gyroscope  536 , motion sensor  538 , and/or a combination thereof, all of which can be operatively connected to I/O section  514 . 
     Memory  518  of personal electronic device  500  can include one or more non-transitory computer-readable storage mediums, for storing computer-executable instructions, which, when executed by one or more computer processors  516 , for example, can cause the computer processors to perform the techniques described below, including process  700  ( FIGS.  7 A- 7 C ). A computer-readable storage medium can be any medium that can tangibly contain or store computer-executable instructions for use by or in connection with the instruction execution system, apparatus, or device. In some examples, the storage medium is a transitory computer-readable storage medium. In some examples, the storage medium is a non-transitory computer-readable storage medium. The non-transitory computer-readable storage medium can include, but is not limited to, magnetic, optical, and/or semiconductor storages. Examples of such storage include magnetic disks, optical discs based on CD, DVD, or Blu-ray technologies, as well as persistent solid-state memory such as flash, solid-state drives, and the like. Personal electronic device  500  is not limited to the components and configuration of  FIG.  5 B , but can include other or additional components in multiple configurations. 
     As used here, the term “affordance” refers to a user-interactive graphical user interface object that is, optionally, displayed on the display screen of devices  100 ,  300 , and/or  500  ( FIGS.  1 A,  3 , and  5 A- 5 B ). For example, an image (e.g., icon), a button, and text (e.g., hyperlink) each optionally constitute an affordance. 
     As used herein, the term “focus selector” refers to an input element that indicates a current part of a user interface with which a user is interacting. In some implementations that include a cursor or other location marker, the cursor acts as a “focus selector” so that when an input (e.g., a press input) is detected on a touch-sensitive surface (e.g., touchpad  355  in  FIG.  3    or touch-sensitive surface  451  in  FIG.  4 B ) while the cursor is over a particular user interface element (e.g., a button, window, slider, or other user interface element), the particular user interface element is adjusted in accordance with the detected input. In some implementations that include a touch screen display (e.g., touch-sensitive display system  112  in  FIG.  1 A  or touch screen  112  in  FIG.  4 A ) that enables direct interaction with user interface elements on the touch screen display, a detected contact on the touch screen acts as a “focus selector” so that when an input (e.g., a press input by the contact) is detected on the touch screen display at a location of a particular user interface element (e.g., a button, window, slider, or other user interface element), the particular user interface element is adjusted in accordance with the detected input. In some implementations, focus is moved from one region of a user interface to another region of the user interface without corresponding movement of a cursor or movement of a contact on a touch screen display (e.g., by using a tab key or arrow keys to move focus from one button to another button); in these implementations, the focus selector moves in accordance with movement of focus between different regions of the user interface. Without regard to the specific form taken by the focus selector, the focus selector is generally the user interface element (or contact on a touch screen display) that is controlled by the user so as to communicate the user&#39;s intended interaction with the user interface (e.g., by indicating, to the device, the element of the user interface with which the user is intending to interact). For example, the location of a focus selector (e.g., a cursor, a contact, or a selection box) over a respective button while a press input is detected on the touch-sensitive surface (e.g., a touchpad or touch screen) will indicate that the user is intending to activate the respective button (as opposed to other user interface elements shown on a display of the device). 
     As used in the specification and claims, the term “characteristic intensity” of a contact refers to a characteristic of the contact based on one or more intensities of the contact. In some embodiments, the characteristic intensity is based on multiple intensity samples. The characteristic intensity is, optionally, based on a predefined number of intensity samples, or a set of intensity samples collected during a predetermined time period (e.g., 0.05, 0.1, 0.2, 0.5, 1, 2, 5, 10 seconds) relative to a predefined event (e.g., after detecting the contact, prior to detecting liftoff of the contact, before or after detecting a start of movement of the contact, prior to detecting an end of the contact, before or after detecting an increase in intensity of the contact, and/or before or after detecting a decrease in intensity of the contact). A characteristic intensity of a contact is, optionally, based on one or more of: a maximum value of the intensities of the contact, a mean value of the intensities of the contact, an average value of the intensities of the contact, a top 10 percentile value of the intensities of the contact, a value at the half maximum of the intensities of the contact, a value at the 90 percent maximum of the intensities of the contact, or the like. In some embodiments, the duration of the contact is used in determining the characteristic intensity (e.g., when the characteristic intensity is an average of the intensity of the contact over time). In some embodiments, the characteristic intensity is compared to a set of one or more intensity thresholds to determine whether an operation has been performed by a user. For example, the set of one or more intensity thresholds optionally includes a first intensity threshold and a second intensity threshold. In this example, a contact with a characteristic intensity that does not exceed the first threshold results in a first operation, a contact with a characteristic intensity that exceeds the first intensity threshold and does not exceed the second intensity threshold results in a second operation, and a contact with a characteristic intensity that exceeds the second threshold results in a third operation. In some embodiments, a comparison between the characteristic intensity and one or more thresholds is used to determine whether or not to perform one or more operations (e.g., whether to perform a respective operation or forgo performing the respective operation), rather than being used to determine whether to perform a first operation or a second operation. 
     In some embodiments, a portion of a gesture is identified for purposes of determining a characteristic intensity. For example, a touch-sensitive surface optionally receives a continuous swipe contact transitioning from a start location and reaching an end location, at which point the intensity of the contact increases. In this example, the characteristic intensity of the contact at the end location is, optionally, based on only a portion of the continuous swipe contact, and not the entire swipe contact (e.g., only the portion of the swipe contact at the end location). In some embodiments, a smoothing algorithm is, optionally, applied to the intensities of the swipe contact prior to determining the characteristic intensity of the contact. For example, the smoothing algorithm optionally includes one or more of: an unweighted sliding-average smoothing algorithm, a triangular smoothing algorithm, a median filter smoothing algorithm, and/or an exponential smoothing algorithm. In some circumstances, these smoothing algorithms eliminate narrow spikes or dips in the intensities of the swipe contact for purposes of determining a characteristic intensity. 
     The intensity of a contact on the touch-sensitive surface is, optionally, characterized relative to one or more intensity thresholds, such as a contact-detection intensity threshold, a light press intensity threshold, a deep press intensity threshold, and/or one or more other intensity thresholds. In some embodiments, the light press intensity threshold corresponds to an intensity at which the device will perform operations typically associated with clicking a button of a physical mouse or a trackpad. In some embodiments, the deep press intensity threshold corresponds to an intensity at which the device will perform operations that are different from operations typically associated with clicking a button of a physical mouse or a trackpad. In some embodiments, when a contact is detected with a characteristic intensity below the light press intensity threshold (e.g., and above a nominal contact-detection intensity threshold below which the contact is no longer detected), the device will move a focus selector in accordance with movement of the contact on the touch-sensitive surface without performing an operation associated with the light press intensity threshold or the deep press intensity threshold. Generally, unless otherwise stated, these intensity thresholds are consistent between different sets of user interface figures. 
     An increase of characteristic intensity of the contact from an intensity below the light press intensity threshold to an intensity between the light press intensity threshold and the deep press intensity threshold is sometimes referred to as a “light press” input. An increase of characteristic intensity of the contact from an intensity below the deep press intensity threshold to an intensity above the deep press intensity threshold is sometimes referred to as a “deep press” input. An increase of characteristic intensity of the contact from an intensity below the contact-detection intensity threshold to an intensity between the contact-detection intensity threshold and the light press intensity threshold is sometimes referred to as detecting the contact on the touch-surface. A decrease of characteristic intensity of the contact from an intensity above the contact-detection intensity threshold to an intensity below the contact-detection intensity threshold is sometimes referred to as detecting liftoff of the contact from the touch-surface. In some embodiments, the contact-detection intensity threshold is zero. In some embodiments, the contact-detection intensity threshold is greater than zero. 
     In some embodiments described herein, one or more operations are performed in response to detecting a gesture that includes a respective press input or in response to detecting the respective press input performed with a respective contact (or a plurality of contacts), where the respective press input is detected based at least in part on detecting an increase in intensity of the contact (or plurality of contacts) above a press-input intensity threshold. In some embodiments, the respective operation is performed in response to detecting the increase in intensity of the respective contact above the press-input intensity threshold (e.g., a “down stroke” of the respective press input). In some embodiments, the press input includes an increase in intensity of the respective contact above the press-input intensity threshold and a subsequent decrease in intensity of the contact below the press-input intensity threshold, and the respective operation is performed in response to detecting the subsequent decrease in intensity of the respective contact below the press-input threshold (e.g., an “up stroke” of the respective press input). 
     In some embodiments, the device employs intensity hysteresis to avoid accidental inputs sometimes termed “jitter,” where the device defines or selects a hysteresis intensity threshold with a predefined relationship to the press-input intensity threshold (e.g., the hysteresis intensity threshold is X intensity units lower than the press-input intensity threshold or the hysteresis intensity threshold is 75%, 90%, or some reasonable proportion of the press-input intensity threshold). Thus, in some embodiments, the press input includes an increase in intensity of the respective contact above the press-input intensity threshold and a subsequent decrease in intensity of the contact below the hysteresis intensity threshold that corresponds to the press-input intensity threshold, and the respective operation is performed in response to detecting the subsequent decrease in intensity of the respective contact below the hysteresis intensity threshold (e.g., an “up stroke” of the respective press input). Similarly, in some embodiments, the press input is detected only when the device detects an increase in intensity of the contact from an intensity at or below the hysteresis intensity threshold to an intensity at or above the press-input intensity threshold and, optionally, a subsequent decrease in intensity of the contact to an intensity at or below the hysteresis intensity, and the respective operation is performed in response to detecting the press input (e.g., the increase in intensity of the contact or the decrease in intensity of the contact, depending on the circumstances). 
     For ease of explanation, the descriptions of operations performed in response to a press input associated with a press-input intensity threshold or in response to a gesture including the press input are, optionally, triggered in response to detecting either: an increase in intensity of a contact above the press-input intensity threshold, an increase in intensity of a contact from an intensity below the hysteresis intensity threshold to an intensity above the press-input intensity threshold, a decrease in intensity of the contact below the press-input intensity threshold, and/or a decrease in intensity of the contact below the hysteresis intensity threshold corresponding to the press-input intensity threshold. Additionally, in examples where an operation is described as being performed in response to detecting a decrease in intensity of a contact below the press-input intensity threshold, the operation is, optionally, performed in response to detecting a decrease in intensity of the contact below a hysteresis intensity threshold corresponding to, and lower than, the press-input intensity threshold. 
     Attention is now directed towards embodiments of user interfaces (“UI”) and associated processes that are implemented on an electronic device, such as portable multifunction device  100 , device  300 , device  500 , computer system  600 , or computer system  654 . 
       FIGS.  6 A- 6 U  illustrate exemplary user interfaces for enrolling a biometric feature for use with a peripheral device, in accordance with some embodiments. The user interfaces in these figures are used to illustrate the processes described below, including the processes in  FIGS.  7 A- 7 C . 
       FIG.  6 A  illustrates computer system  600  connected to peripheral device  602  (e.g., an external keyboard that is not integrated with computer system) and displaying, via display  604 , setup user interface  606 . At  FIG.  6 A , computer system  600  is wirelessly connected to peripheral device  602 , as indicated by dashed line  608 . When computer system  600  is connected to peripheral device  602  (e.g., wirelessly connected), computer system  600  is configured to detect user inputs at one or more input devices (e.g., keys of a keyboard) of peripheral device  602  and to perform corresponding operations based on the detected user inputs. As discussed in detail below, even when computer system  600  is connected to peripheral device  602 , computer system  600  can prompt (e.g., require) a user to provide an authorization input (e.g., an input that confirms a user is in possession of both computer system  600  and peripheral device  602 ) before enabling peripheral device  602  to be used to authenticate a secure operation at computer system  600 . While dashed line  608  is shown in  FIG.  6 A , it should be understood that dashed line  608  indicates a wireless communication (e.g., wireless transmission of data) between computer system  600  and peripheral device  602  and does not represent a physical device, a physical item, and/or an object displayed via display  604  (e.g., dashed line  608  does not represent a physical connection between computer system  600  and peripheral device  602 , such as a wire establishing a wired connection). In some embodiments, the wireless connection between computer system  600  and peripheral device  602  includes a short-range communication technique (e.g., a Bluetooth connection). In some embodiments, the wireless connection between computer system  600  and peripheral device  602  includes a Wi-Fi connection, a Zigbee connection, and/or another suitable wireless connection. 
     At  FIG.  6 A , computer system  600  is a notebook computer system (e.g., a laptop computer) that includes first portion  600   a  having display  604  and second portion  600   b  having at least one input device of input devices  610  physically connected to computer system  610 . First portion  600   a  and second portion  600   b  are connected to one another via a hinged connection (e.g., first portion  600   a  and/or second portion  600   b  are configured to at least partially rotate about an axis at a connection point between first portion  600   a  and second portion  600   b ). At  FIG.  6 A , computer system  600  is in an open position (e.g., first portion  600   a  and second portion  600   b  are positioned with respect to one another to form an angle that is between 30 degrees and 150 degrees, between 45 degrees and 135 degrees, or between 60 degrees and 120 degrees), such that input devices  610  are accessible by, and/or capable of interaction via, a user associated with computer system  600  and display  604  is visible. First portion  600   a  (and/or second portion  600   b ) can be manually adjusted to a second position (e.g., a closed position illustrated at  FIG.  6 G ), such that first portion  600   a  covers surface  600   c  (e.g., a surface that enables access to and/or user interaction with input devices  610 ) of second portion  600   b  and second portion  600   b  covers display  604 . 
     Input devices  610  of computer system  600  include keyboard  610   a  (e.g., a physical keyboard that includes depressible buttons), trackpad  610   b  (e.g., a touch-sensitive surface and/or component that detects finger contacts and/or movements of the finger contacts of a user), integrated biometric sensor  610   c  (e.g., a fingerprint sensor), and camera  610   d . In some embodiments, integrated biometric sensor  610   c  includes a depressible button in addition to a biometric sensor (e.g., the biometric sensor includes a film and/or scanning device deposited on and/or within the depressible button). In some embodiments, integrated biometric sensor  610   c  is a power button of computer system  600  that is configured to cause computer system  600  to transition between an on state, an off state, and/or an idle state in response to detecting user input (e.g., powering down the computer system in response to detecting that the power button has been depressed for at least a threshold duration of time). At  FIG.  6 A , integrated biometric sensor  610   c  is included within housing  600   d  (e.g., at least partially disposed within housing  600   d ) of computer system  600  (e.g., second portion  600   b  of computer system  600 ). In other words, integrated biometric sensor  610   c  is physically connected to computer system  600  and is not intended to be removed during normal operation of computer system  600  and/or integrated biometric sensor  610   c  is part of computer system  600 . In some embodiments, integrated biometric sensor  610   c  is physically connected, via a wired connection, to one or more processors included within housing  600   d  (e.g., completely disposed within housing  600   d ). In some embodiments, integrated biometric sensor  610   c  is configured to detect user inputs and/or cause computer system  600  to perform particular actions using an operating system software of computer system  600  (e.g., computer system  600  does not require software in addition to the operating system software to be installed in order for computer system  600  to detect user inputs directed at the integrated biometric sensor  610   c ). 
     In some embodiments, camera  610   d  is included within housing  600   d  (e.g., at least partially disposed within housing  600   d ) of computer system  600  (e.g., first portion  600   a  of computer system  600 ). In other words, camera  610   d  is physically connected to computer system  600 , camera  610   d  is not intended to be removed during normal operation of computer system  600 , and/or camera  610   d  is part of computer system  600 . In some embodiments, camera  610   d  is physically connected, via a wired connection, to one or more processors included within housing  600   d  (e.g., completely disposed within housing  600   d ). In some embodiments, camera  610   d  is configured to capture one or more images in response to instructions of an operating system software of computer system  600  (e.g., computer system  600  does not require software in addition to the operating system software to be installed in order for camera  610   d  to capture images that include biometric features of a user for authenticating a secure operation at computer system  600 ). 
     In addition, peripheral device  602  includes input devices  612  that, when selected via user input, are configured to cause computer system  600  to perform various functions when peripheral device  602  is connected to computer system  600 . Input devices  612  of peripheral device  602  include keyboard  612   a  (e.g., a physical keyboard that includes depressible buttons), trackpad  612   b  (e.g., a surface and/or component that detects finger contacts and/or movements of the finger contacts of a user), and biometric sensor  612   c  (e.g., a biometric sensor that is integrated with (e.g., disposed in a housing of) peripheral device  602 ). In some embodiments, peripheral device  602  further includes a camera and/or a microphone as input devices  612 . In some embodiments, input devices  612  of peripheral device  602  cause computer system  600  to perform similar (or the same) functions as keyboard  610   a , trackpad  610   b , and integrated biometric sensor  610   c  of computer system (e.g., when peripheral device  602  is connected to computer system  600 ). For instance, integrated biometric sensor  610   c  and biometric sensor  612   c  are both configured to detect data about a biometric feature (e.g., a fingerprint) when a user places a body part (e.g., a finger) in proximity to, and/or in contact with, integrated biometric sensor  610   c  and biometric sensor  612   c . In response to detecting the data about the biometric feature, computer system  600  receives the data (e.g., from integrated biometric sensor  610   c  and/or biometric sensor  612   c ) and compares the data to data about an enrolled biometric feature of computer system  600 . When the data about the biometric feature corresponds to and/or matches data about the enrolled biometric feature of computer system  600 , computer system  600  can perform a secure operation (e.g., an operation that requires authorization of a user associated with computer system  600 ). As set forth below, the secure operation can include completion of a transaction, a transition of computer system  600  between operating modes (e.g., a locked mode and an unlocked mode), and/or accessing secure documents, an account, and/or software of computer system  600 . 
     At  FIG.  6 A , setup user interface  606  includes connection indicator  606   a , continue user interface object  606   b , and back user interface object  606   c . While setup user interface  606  is displayed as a window that partially covers an area of display  604 , in some embodiments, setup user interface  606  covers an entire area of display  604  (e.g., setup user interface  606  is displayed, via display  604 , as a maximized window). In some embodiments, setup user interface  606  is one user interface that is included in a series of user interfaces during an initial setup process of computer system  600  (e.g., a setup process initiated by computer system  600  upon first powering on computer system  600 , a setup process initiated by computer system  600  upon resetting one or more operating parameters of computer system  600 , and/or a setup process initiated by computer system  600  upon adding and/or associating a new user account with computer system). 
     At  FIG.  6 A , setup user interface  606  corresponds to a keyboard connection step of the setup process. Connection indicator  606   a  includes a visual indication (e.g., a textual indication and/or a check mark) that peripheral device  602  has successfully been connected to computer system  600 . In some embodiments, a previous step of the setup process prompts the user associated with computer system  600  to initiate the connection between peripheral device  602  and computer system  600  (e.g., the user is prompted to provide user input to an input device of input devices  610  and/or an input device of input devices  612  to initiate the connection between peripheral device  602  and computer system  600 ). In some embodiments, in response to detecting that a connection has been established between peripheral device  602  and computer system  600 , computer system  600  displays, via display  604 , setup user interface  606 . 
     At  FIG.  6 A , computer system  600  detects user input  650   a  (e.g., a mouse click, a tap and/or press gesture on trackpad  610   b  and/or trackpad  612   b , a tap gesture on display  604  (such as when display  604  is a touch-sensitive display), and/or a press gesture on a particular key (e.g., an “Enter” and/or “Return” key) of keyboard  610   a  and/or keyboard  612   a ). In response to detecting user input  650   a , computer system  600  displays, via display  604 , enrollment user interface  614  (e.g., biometric feature enrollment user interface), as shown at  FIGS.  6 B and  6 C . 
     In some embodiments, computer system  600  displays enrollment user interface  614  in accordance with a determination that computer system  600  does not include data associated with an enrolled biometric feature. In other words, computer system  600  displays enrollment user interface  614 , which prompts a user to enroll a biometric feature, when computer system  600  does not include an enrolled biometric feature. An enrolled biometric feature optionally includes data about a biometric feature (e.g., a fingerprint, one or more facial features and/or characteristics, one or more iris features and/or characteristics, and/or speech characteristics of the user associated with the computer system) that is stored in memory of computer system  600  (e.g., and/or memory accessible by computer system  600 ). Computer system  600  utilizes the stored data about the enrolled biometric feature to make a determination as to whether data about a detected biometric feature (e.g., data detected via integrated biometric sensor  610   c  and/or biometric sensor  612   c ) matches (e.g., completely matches, partially matches, and/or a threshold amount of data matches) the stored data about the enrolled biometric feature. 
     When computer system  600  determines that the data about the detected biometric feature matches the stored data about the enrolled biometric feature, computer system  600  is configured to authorize a secure operation (e.g., completing of a transaction, transitioning computer system  600  between one or more modes of operation (e.g., a locked mode, an idle mode, a normal operating mode, and/or an unlocked mode), initiating downloading software, and/or providing access to a document and/or application) to be performed at computer system  600 . When computer system  600  determines that the data about the detected biometric feature does not match the stored data about the enrolled biometric feature, computer system  600  does not authorize the secure operation at computer system  600  (and, instead, computer system  600  optionally displays, via display  604 , an error user interface, a rejection user interface, and/or a user interface prompting the user to provide and/or re-provide a user input that includes data associated with a biometric feature (e.g., a finger contact on integrated biometric sensor  610   c  and/or biometric sensor  612   c )). 
     At  FIGS.  6 B and  6 C , enrollment user interface  614  includes visual indicator  614   a  (e.g., textual indication) prompting a user to provide a user input (e.g., a finger contact) on integrated biometric sensor  610   c  and/or biometric sensor  612   c , back user interface object  614   b , and continue user interface object  614   c . As shown at  FIGS.  6 B and  6 C , continue user interface object  614   c  includes an appearance (e.g., a greyed coloring and/or dimmed brightness level) that is different from an appearance of back user interface object  614   b  (e.g., a non-grey coloring and/or a normal brightness level). As such, computer system  600  indicates that to proceed with the setup process, the user should provide the user input prompted by visual indicator  614   a  (e.g., user cannot select continue user interface object  614   c  before providing the user input prompted by visual indicator  614   a ). In some embodiments, enrollment user interface  614  also includes a skip user interface object that enables a user to skip (e.g., bypass and/or not complete) a sub-process for enrolling a biometric feature and continue with the setup process. In such embodiments, a user can enroll a biometric feature at a later time by accessing a settings user interface of computer system  600 . 
     At  FIG.  6 B , computer system  600  detects user input  650   b  (e.g., a finger contact) on integrated biometric sensor  610   c  of computer system  600 . In response to detecting user input  650   b , computer system  600  receives data about a biometric feature (e.g., a fingerprint) from user input  650   b . In some embodiments, integrated biometric sensor  610   c  is a capacitive sensor that collects data about the biometric feature using one or more capacitor circuits. In some embodiments, integrated biometric sensor  610   c  is an optical sensor and collects data about the biometric feature using a camera and/or light emissions. In response to receiving data about the biometric feature, computer system  600  displays acquisition user interface  618 , as shown at  FIG.  6 E . 
     At  FIG.  6 C , computer system  600  displays enrollment user interface  614  and detects user input  650   c  (e.g., a finger contact) on biometric sensor  612   c  of peripheral device  602 . Similar to  FIG.  6 B , in response to detecting user input  650   c , computer system  600  receives data about a biometric feature (e.g., a fingerprint) from user input  650   c . In contrast to  FIG.  6 B , computer system  600  displays verification user interface  616 , at  FIG.  6 D , in response to receiving data about the biometric feature from user input  650   c  and/or based on a determination that user input  650   c  was detected at biometric sensor  612   c  of peripheral device  602 . Because peripheral device  602  is a separate component from, and/or not integrated with, computer system  600 , computer system  600  displays verification user interface  616  to confirm that a user in possession of peripheral device is the same user in possession of computer system  600 . Thus, by displaying verification user interface  616 , computer system  600  includes enhanced security by preventing and/or blocking a user that is not in possession of computer system  600  from enrolling a biometric feature that can be used to authorize secure operations at computer system  600 . 
     For instance, at  FIG.  6 D , verification user interface  616  includes visual indicator  616   a  (e.g., textual indications) prompting a user to provide an authorization input (e.g., an authorization user input) corresponding to an input device of input devices  610  of computer system  600 . Because input devices  610  are integrated with (e.g., physically connected to and/or a part of) computer system  600 , detecting an input at an input device of input devices  610  of computer system  600  ensures that the user enrolling the biometric feature using biometric sensor  612   c  of peripheral device is also in possession of (e.g., and/or in close proximity to) computer system  600 . At  FIG.  6 D , visual indicator  616   a  prompts a user to perform the authorization input by double pressing integrated biometric sensor  610   c . As set forth above, integrated biometric sensor  610   c  can also be a power button of computer system  600 . 
     In some embodiments, visual indicator  616   a  optionally prompts the user to perform the authorization input via a single press of integrated biometric sensor  610   c , a single press and/or a double press of a button of keyboard  610   b , a tap gesture and/or press gesture on trackpad  610   b , and/or another user input on one of input devices  610  that are part of and/or physically connected to computer system  600 . 
     At  FIG.  6 D , computer system  600  detects user input  650   d , which includes the authorization input prompted via verification user interface  616  (e.g., a double press of integrated biometric sensor  616   c ). In response to detecting user input  650   d  and based on a determination that user input  650   d  includes the authorization input, computer system  600  displays acquisition user interface  618 , as shown at  FIG.  6 E . 
     At  FIG.  6 E , computer system  600  displays acquisition user interface  618 , which enables a user to complete the enrollment process of the biometric feature that is detected via integrated biometric sensor  610   c  (e.g., from user input  650   b ) and/or biometric sensor  612   c  (e.g., from user input  650   c ). Acquisition user interface  618  includes visual indicator  618   a  (e.g., textual indications) providing instructions to the user associated with computer system to perform one or more user inputs and/or actions to complete enrollment of the biometric feature. At  FIG.  6 E , visual indicator  618   a  indicates that a user should rest their finger on integrated biometric sensor  610   c  and/or biometric sensor  612   c . Further, visual indicator  618   a  instructs the user to lift and re-position (e.g., rest) their finger on integrated biometric sensor  610   c  and/or biometric sensor  612   c . In some embodiments, enrollment indicator  618   b  of acquisition user interface  618  is updated in response to integrated biometric sensor  610   c  and/or biometric sensor  612   c  detecting one or more finger contacts of the user (e.g., a sequence of finger contacts (e.g., a user resting their finger) separated by lift-offs of the finger contacts). For example, enrollment indicator  618   b  can emphasize (e.g., change a color, thickness, size, and/or brightness of) one or more portions of enrollment indicator  618   b  (e.g., represented as grooves and/or ridges of a fingerprint) in response to a finger contact detected by integrated biometric sensor  610   c  and/or biometric sensor  612   c . Updating enrollment indicator  618   b  provides an indication of a progress toward completion of the enrollment process (e.g., indicates how many additional finger contacts a user should provide in order to complete enrollment of their fingerprint). 
     In response to detecting that the biometric feature of the user has been completed (e.g., a sufficient number of finger contacts separated by finger lift-offs have been detected by integrated biometric feature  610   c  and/or biometric sensor  612   c  to identify a fingerprint of the user), computer system  600  displays confirmation user interface  620 , as shown at  FIG.  6 F . At  FIG.  6 F , confirmation user interface  620  includes visual indicator  620   a  (e.g., textual indication) indicating that the biometric feature has been successfully enrolled, visual indicator  620   b  (e.g., a graphic and/or image) indicating a type of biometric feature enrolled (e.g., fingerprint), and done user interface object  620   c . Visual indicator  620   a  and visual indicator  620   b  provide confirmation to the user that the biometric feature has been successfully enrolled and that the user may utilize the biometric feature (e.g., the fingerprint of the user) to authorize computer system  600  to perform a secure operation. In some embodiments, in response to detecting user input corresponding to done user interface object  620   c , computer system  600  continues the setup process and displays an additional user interface corresponding to the next step of the setup process. In some embodiments, in response to detecting user input corresponding to done user interface object  620   c , computer system  600  displays a home screen user interface and/or a desktop user interface corresponding to a normal operating mode of computer system (e.g., an unlocked mode). 
     While,  FIGS.  6 B- 6 F  illustrate enrolling a fingerprint as the biometric feature, in some embodiments, the enrolled biometric feature may be a face (e.g., one or more facial features and/or characteristics), eyes (e.g., one or more features and/or characteristics of an iris), and/or speech (e.g., one or more characteristics of a voice) of a user. Accordingly, in some embodiments, computer system  600  detects and/or receives data about a biometric feature via camera  610   d  (and/or a camera of peripheral device  602 ) and/or a microphone of computer system  600  (and/or a microphone of peripheral device  602 ). In such embodiments, enrollment user interface  614  can include one or more indicators prompting a user to position their face and/or eyes within a particular field of view of camera  610   d  and/or to speak one or more words (e.g., to be detected via a microphone of computer system). As such, it should be understood that the present disclosure is not limited to enrolling a fingerprint and subsequently using the fingerprint to authorize secure operations at computer system  600 . 
     As set forth above, computer system  600  includes first portion  600   a  and second portion  600   b , which can be rotated with respect to one another to place computer system  600  in a closed position. At  FIG.  6 G , computer system  600  is in the closed position and connected to external display  622  (as represented by dashed line  624 ), as well as connected to peripheral device  602  (as represented by dashed line  608 ). When connected to external display  622 , computer system  600  is configured to display user interfaces and/or user interface objects associated with instructions stored in memory of computer system on external display  622 . At  FIG.  6 G , computer system  600  and external display  622  are connected to one another via a wireless connection, as indicated by dashed line  624 . In some embodiments, the wireless connection between computer system  600  and external display  622  is a short-range communication (e.g., a Bluetooth connection). In some embodiments, the wireless connection between computer system  600  and external display  622  is a Zigbee and/or Wi-Fi connection. In some embodiments, computer system  600  and external display  622  are connected to one another via a wired connection. In some embodiments, computer system  600  is connected to external display  622  via a docking device (e.g., a physical component that is configured to establish communication (e.g., transfer of data) between computer system and external display  622 ). 
     In some embodiments, computer system  600  is connected to external display  622  and connected to peripheral device  602  during the initial setup process and/or when computer system  600  does not include an enrolled biometric feature (e.g., computer system  600  does not store and/or have access to stored data about an enrolled biometric feature; the user has not completed the enrollment process for a biometric feature, such as the process described above with reference to  FIG.  6 B ,  FIG.  6 E , and/or  FIG.  6 F ). In some embodiments, computer system  600  is connected to external display  622  and connected to peripheral device  602  after completing the initial setup process and/or when computer system  600  includes an enrolled biometric feature (e.g., computer system stores and/or has access to stored data about an enrolled biometric feature; the user has completed the enrollment process for a biometric feature, such as the process described above with reference to  FIG.  6 B ,  FIG.  6 E , and/or  FIG.  6 F ). 
     At  FIG.  6 G , computer system detects user input  650   e  (e.g., a finger contact) on biometric sensor  612   c  of peripheral device  602 . In response to detecting user input  650   e , computer system  600  determines whether computer system  600  includes an enrolled biometric feature. At  FIG.  6 G , computer system  600  determines that computer system  600  does not include an enrolled biometric feature and/or that data about a biometric feature received from user input  650   e  (e.g., detected by biometric sensor  612   c ) does not correspond to (e.g., match) data about the enrolled biometric feature. Based on the determination that computer system  600  does not include an enrolled biometric feature and/or that the data about the biometric feature received from user input  650   e  (e.g., detected by biometric sensor  612   c ) does not correspond to data about the enrolled biometric feature, computer system  600  displays, via external display  622 , verification user interface  626 . 
     At  FIG.  6 G , because computer system  600  is in the closed position (e.g., first portion  600   a  of computer system  600  covers and/or blocks access to integrated biometric sensor  610   c ), verification user interface  626  includes visual indicator  626   a  (e.g., textual indicator) prompting a user to adjust a position of computer system  600  (e.g., adjust a position of first portion  600   a  and/or second portion  600   b  with respect to one another) to the open position (e.g., the position of computer system  600  in  FIGS.  6 A- 6 F ; a position of computer system  600  where first portion  600   a  does not cover and/or block access to integrated biometric sensor  610   c  of computer system  600 ). In addition, visual indicator  626   a  prompts the user to provide the authorization input (e.g., a double press gesture on integrated biometric sensor  610   c ) to an input device of the input devices  610  physically connected to computer system  600 . As set forth above, the authorization input provides confirmation to computer system  600  that a user providing user input  650   e  is in possession of both computer system  600  and peripheral device  602  (e.g., the user is in close proximity to and/or is the same user of both computer system  600  and peripheral device  602 ), thereby improving a security of computer system  600  (e.g., by preventing an unauthorized user from enrolling a biometric feature with peripheral device  602 ). 
     As set forth above, in some embodiments, computer system  600  is connected to external display  622  and connected to peripheral device  602  when computer system  600  includes an enrolled biometric feature. Based on a determination that data about the biometric feature received via user input  650   e  corresponds to data about the enrolled biometric feature of computer system  600 , computer system  600  enables the enrolled biometric feature to be used by peripheral device  602  (e.g., via input detected by biometric sensor  612   c ) to authorize a secure operation at computer system  600 . In other words, when computer system  600  includes an enrolled biometric feature and when data about a detected biometric feature received via user input on biometric sensor  612   c  of peripheral device  602  corresponds to data about the enrolled biometric feature, computer system  600  enables user inputs that authorize secure operations at computer system  600  to be received and/or detected at peripheral device  602 . In addition, computer system  600  does not display verification user interface  626  based on a determination that data about the detected biometric feature corresponds data about the enrolled biometric feature. As such, computer system  600  determines that the user of peripheral device  602  is the same user as computer system  600  because data about the detected biometric feature corresponds to data about the enrolled biometric feature (e.g., the fingerprint detected at biometric sensor  612   c  is determined to match an enrolled fingerprint of computer system  600 ). In some embodiments, computer system  600  enables the enrolled biometric feature to be utilized by peripheral device  602  to authorize a secure operation at computer system  600  and forgoes displaying verification user interface  626  (and/or verification user interface  616 ) when data about the detected biometric feature (e.g., detected via biometric sensor  612   c  of peripheral device  602 ) corresponds to data about the enrolled biometric feature regardless of a position of computer system  600  (e.g., regardless of whether computer system  600  is in the open position or the closed position). 
     As set forth above with reference to  FIGS.  6 A- 6 F , computer system  600  and peripheral device  602  are connected to one another via a wireless connection (e.g., as represented by dashed line  608 ). However, computer system  600  and peripheral device  602  can also be connected to one another via a wired connection (e.g., a wired communication). At  FIG.  6 H , computer system  600  and peripheral device  602  are connected via cable  628  that establishes the wired connection between computer system  600  and peripheral device  602 . At  FIG.  6 H , computer system  600  displays, via display  604 , enrollment user interface  629  prompting a user to provide an enrollment input (e.g., a finger contact on integrated biometric sensor  610   c  and/or a finger contact on biometric sensor  612   c ). 
     At  FIG.  6 H , computer system  600  detects user input  650   f  at biometric sensor  612   c  of peripheral device  602 . Regardless of whether computer system  600  includes an enrolled biometric feature (and, optionally, regardless of whether computer system  600  is in the open position or the closed position), in response to detecting user input  650   f , computer system  600  forgoes displaying a verification user interface and enrolls (or begins to enroll) a detected biometric feature of user input  650   f  and/or enables use of biometric sensor  612   c  of peripheral device  602  to authorize a secure operation at computer system  600  (e.g., without requiring and/or detecting the authorization input). Computer system  600  forgoes displaying verification user interface because computer system  600  determines that peripheral device  602  is connected via cable  628 , and therefore, that the user associated with computer system  600  connected peripheral device  602  and/or that the user associated with computer system  600  is in possession of (e.g., in close proximity to) both computer system and peripheral device  602 . Accordingly, computer system  600  does not display verification user interface because the wired connection between computer system  600  and peripheral device  602  confirms that a user is in possession of both computer system  600  and peripheral device  602 . 
     As set forth above, peripheral device  602  can be connected to computer system  600  after the setup process (e.g., the initial setup process of computer system  600 ).  FIGS.  61  and  6 J  illustrate exemplary embodiments for connecting peripheral device  602  to computer system  600  after the setup process. At  FIG.  6 I , computer system  600  displays, via display  604  (and/or, in some embodiments, via external display  622 , instead), first settings user interface  630  (e.g., Bluetooth settings user interface). First settings user interface  630  includes first settings indicator  630   a  (e.g., a visual indicator of a first setting of computer system  600  (e.g., Bluetooth setting)), first settings user interface object  630   b , and device user interface object  630   c . At  FIG.  6 I , first settings user interface  630  corresponds to a short-range communication settings user interface that enables computer system  600  to connect to one or more external devices via a short-range communication connection (e.g., a wireless, Bluetooth connection). In response to detecting user input corresponding to selection of first settings user interface object  630   b , computer system  600  is configured to enable and/or disable detection of external devices capable of connecting to computer system  600  via a short-range communication connection. At  FIG.  6 I , first settings user interface object  630   b  is in an active position indicating that computer system  600  is detecting external devices within range (e.g., a threshold distance of) computer system  600  that are capable of connecting to computer system  600  via a short-range communication connection. 
     Device user interface object  630   c  includes a list of one or more external devices detected by computer system  600 , one or more external devices with which computer system  600  has previously established a short-range communication connection, and/or one or more external devices with which computer system  600  has an established short-range communication connection. At  FIG.  6 I , device user interface object  630   c  includes first device user interface object  630   d  corresponding to peripheral device  602 . In addition, computer system  600  displays connection status indicator  630   e  indicating that computer system  600  is currently establishing a short-range communication connection with peripheral device  602 . In some embodiments, prior to displaying connections status indicator  630   e , computer system  600  displays a connect user interface object in place of connection status indicator  630   e , that, when selected via user input, initiates the short-range communication connection with peripheral device  602 . In response to detecting an established connection between computer system  600  and peripheral device  602 , computer system  600  displays enrollment user interface  634 , as shown at  FIG.  6 K . In some embodiments, computer system  600  displays enrollment user interface  634  in response to detecting the established connection between computer system  600  and peripheral device  602  and in response to detecting that peripheral device  602  includes a biometric sensor, such as biometric sensor  612   c.    
     At  FIG.  6 J , computer system  600  displays, via display  604  (and/or, in some embodiments, via external display  622 ), second settings user interface  632  (e.g., keyboard settings user interface). Second settings user interface  630  includes second settings indicator  632   a  (e.g., a visual indicator of a second setting of computer system  600  (e.g., keyboard setting)), device indicator  632   b  (e.g., a textual indication of one or more external keyboard devices detected by computer system  600 ), and connection status indicator  632   c . At  FIG.  6 J , second settings user interface  632  corresponds to a keyboard settings user interface that enables computer system  600  to connect to one or more keyboards (e.g., via a wireless connection, such as a Bluetooth connection, a Wi-Fi connection, and/or a Zigbee connection, and/or via a wired connection). In some embodiments, in response to a request to display second settings user interface  632 , computer system  600  is configured to detect external keyboard devices that are capable of connecting to computer system  600 . For instance, device indicator  632   b  indicates that computer system  600  detected peripheral device  602 . In addition, connection status indicator  632   c  indicates that computer system  600  is establishing a connection with peripheral device  602  (e.g., via a wireless connection). In some embodiments, prior to displaying connection status indicator  632   c , computer system  600  displays a connect user interface object in place of connection status indicator  632   c , that, when selected via user input, initiates the connection between computer system  600  and peripheral device  602 . In response to detecting an established connection between computer system  600  and peripheral device  602 , computer system  600  displays enrollment user interface  634 , as shown at  FIG.  6 K . In some embodiments, computer system  600  displays enrollment user interface  634  in response to detecting the established connection between computer system  600  and peripheral device  602  and in response to detecting that peripheral device  602  includes a biometric sensor, such as biometric sensor  612   c.    
     At  FIG.  6 K , enrollment user interface  634  includes initiate enrollment user interface object  634   a  (e.g., a “+” symbol) and is configured to, when selected via user input, enable a user to enroll a biometric feature for use with peripheral device  602  (e.g., computer system  600  receives data from biometric sensor  612   c  of peripheral device  602  to authorize a secure operation at computer system  600 ). In some embodiments, computer system  600  forgoes display of enrollment user interface  634  based on a determination that computer system  600  includes an enrolled biometric feature. 
     At  FIG.  6 K , computer system  600  detects user input  650   g  (e.g., mouse click on initiate enrollment user interface object  634   a , such as a tap gesture and/or press gesture on trackpad  610   b  and/or trackpad  612   b , and/or a touch gesture on initiate enrollment user interface object  634   a  detected via display  604 ). In response to detecting user input  650   g , computer system  600  displays acquisition user interface  636 , as shown at  FIG.  6 L . 
     At  FIG.  6 L , computer system  600  displays acquisition user interface  636 , which enables a user to complete the enrollment process of a biometric feature that is detected via integrated biometric sensor  610   c  and/or biometric sensor  612   c . Acquisition user interface  636  includes visual indicator  636   a  (e.g., textual indications) providing instructions to the user associated with computer system to perform various user inputs and/or actions to complete enrollment of the biometric feature. At  FIG.  6 L , visual indicator  636   a  prompts a user to rest their finger on integrated biometric sensor  610   c  and/or biometric sensor  612   c . Further, visual indicator  636   a  prompts the user to lift and re-position (e.g., rest) their finger on integrated biometric sensor  610   c  and/or biometric sensor  612   c . In some embodiments, computer system  600  detects user input via integrated biometric sensor  610   c . In response to detecting user input via integrated biometric sensor  610   c , enrollment indicator  636   b  of acquisition user interface  636  is updated as integrated biometric sensor  610   c  detects one or more finger contacts of the user (e.g., a sequence of finger contacts (e.g., a user resting their finger) separated by lift-offs of the finger contacts). For example, enrollment indicator  636   b  can emphasize (e.g., change a color, thickness, size, and/or brightness of) one or more portions of enrollment indicator  636   b  (e.g., represented as grooves and/or ridges of a fingerprint) in response to a finger contact detected by integrated biometric sensor  610   c . Updating enrollment indicator  636   b  provides an indication of a progress toward completion of the enrollment process (e.g., indicates how many additional finger contacts and/or lift-offs of finger contacts a user should provide in order to complete enrollment of their fingerprint). When computer system  600  detects user input via integrated biometric sensor  610   c , computer system  600  enables the enrollment of the biometric feature (e.g., a fingerprint) without displaying verification user interface  638  (e.g., as shown at  FIG.  6 M ) and without requiring an authorization input to enroll the biometric feature for use with peripheral device  602 . In addition, computer system  600  enables both integrated biometric sensor  610   c  and biometric sensor  612   c  to detect data about a biometric feature for use in authenticating the user and authorizing a secure operation at computer system  600 . 
     At  FIG.  6 L , computer system  600  detects user input  650   h  (e.g., a finger contact on biometric sensor  612   c ) via biometric sensor  612   c . In some embodiments (e.g., when computer system  600  includes data about an enrolled biometric feature), in response to detecting user input  650   h , computer system  600  compares data about a detected biometric feature (e.g., via biometric sensor  612   c ) to data about an enrolled biometric feature of computer system  600 . When the data about the detected biometric feature corresponds to (e.g., matches and/or a threshold amount of data matches) the data about the enrolled biometric feature, computer system  600  enables peripheral device  602  to be used to authenticate and/or authorize secure operations at computer system  600  (e.g., using biometric feature(s) previously enrolled on computer system  600 , including biometric features that do not match the data about the detected biometric feature provided via user input  650   h ). In some embodiments, when the data about the detected biometric feature does not correspond to (e.g., does not match and/or a threshold amount of data does not match) the data about the enrolled biometric feature, computer system  600  displays verification user interface  638 , as set forth below. In some embodiments, when the data about the detected biometric feature does not correspond to (e.g., does not match and/or a threshold amount of data does not match) the data about the enrolled biometric feature, computer system  600  displays an error user interface and/or a user interface prompting a user to provide and/or re-provide the user input on biometric sensor  612   c.    
     In response to detecting user input  650   h  (and in some embodiments, based on a determination that computer system  600  does not include an enrolled biometric feature and/or that data about a biometric feature detected via biometric sensor  612   c  does not correspond to data about an enrolled biometric feature), computer system  600  displays verification user interface  638 , as shown at  FIG.  6 M . Because peripheral device  602  is a separate component from, and/or not integrated with, computer system  600 , computer system  600  displays verification user interface  638  to confirm that a user in possession of peripheral device is the same user that is in possession of computer system  600 . Thus, by displaying verification user interface  638 , computer system  600  includes enhanced security by preventing and/or blocking a user that is not in possession of computer system  600  from enrolling a biometric feature that can be used to authorize secure operations at computer system  600  (e.g., via peripheral device  602 ). 
     For instance, at  FIG.  6 M , verification user interface  638  includes visual indicator  638   a  (e.g., textual indications) prompting a user to provide an authorization input (e.g., an authorization user input) corresponding to one of input devices  610  of computer system  600  (e.g., an input device integrated with and/or physically connected to computer system  600 ). Because input devices  610  are integrated with (e.g., physically connected to and/or a part of) computer system  600 , detecting an input at one of input devices  610  of computer system  600  ensures that the user enrolling the biometric feature using biometric sensor  612   c  of peripheral device  602  is in possession of (e.g., and/or in close proximity to) computer system  600 . At  FIG.  6 M , visual indicator  638   a  prompts a user to perform the authorization input by double pressing integrated biometric sensor  610   c . As set forth above, integrated biometric sensor  610   c  can also be a power button of computer system  600 . In some embodiments, visual indicator  638   a  can prompt the user to perform the authorization input via a single press of integrated biometric sensor  610   c , a single press and/or a double press of a button included on keyboard  610   b , a tap gesture and/or press gesture on trackpad  610   b , and/or another user input on one of input devices  610  that are part of and/or physically connected to computer system  600 . 
     At  FIG.  6 M , computer system  600  detects user input  650   i  via integrated biometric sensor  610   c . Based on a determination that user input  650   i  includes the authorization input (e.g., a double press gesture on integrated biometric sensor  610   c ), computer system  600  enables enrollment of the biometric feature detected via biometric sensor  612   c  of peripheral device  602 , as set forth above. In some embodiments, based on a determination that user input  650   i  does not include the authorization input (e.g., a gesture that is not a double press gesture on integrated biometric sensor  610   c ), computer system  600  displays, via display  604 , error user interface  668 , as shown at  FIG.  6 U . In some embodiments, based on a determination that user input  650   i  does not include the authorization input, computer system  600  maintains display of, via display  604 , verification user interface  638  and/or displays another user interface prompting a user to provide and/or re-provide the authorization input. 
     In some embodiments, computer system  600  includes an enrolled biometric feature and the authorization input includes authenticating the enrolled biometric feature. For example, in response to detecting user input  650   g  at  FIG.  6 K , computer system  600  displays, via display  604 , acquisition user interface  636 , which enables a user to complete the enrollment process of a biometric feature that is detected via integrated biometric sensor  610   c  and/or biometric sensor  612   c , as shown at  FIG.  6 N . 
     At  FIG.  6 N , computer system  600  detects user input  650   j  via biometric sensor  610   c  of peripheral device  602 , where user input  650   j  includes data about a fingerprint of the user&#39;s index finger. In response to detecting user input  650   j , computer system  600  determines whether the data about the fingerprint of the user&#39;s index finger corresponds to (e.g., matches and/or a threshold amount of data matches) data about the enrolled biometric feature. In some embodiments, when computer system  600  determines that data about the fingerprint of the user&#39;s index finger corresponds to data about the enrolled biometric feature, computer system  600  completes the enrollment process and enables peripheral device  602  to be used to authenticate and/or authorize secure operations at computer system  600  (e.g., using biometric feature(s) previously enrolled on computer system  600 , including biometric features that do not match the data about the detected biometric feature provided via user input  650   j ). 
     At  FIG.  6 N , computer system  600  determines that data about the user&#39;s index finger does not correspond to data about the enrolled biometric feature. Based on the determination that the data about the user&#39;s index finger does not correspond to data about the enrolled biometric feature, computer system  600  displays verification user interface  640 , as shown at  FIG.  6 O . 
     At  FIG.  6 O , computer system  600  displays verification user interface  640  because computer system  600  is unable to authenticate data about a detected biometric feature (e.g., the user&#39;s index finger) to an enrolled biometric feature. In addition, user input  650   j  is detected via an input device of input devices  612  of peripheral device  602 , which can be in the possession of a different user from a user associated with computer system  600 . Therefore, computer system  600  prompts the user to provide the authorization input, which includes an input (e.g., finger contact) on integrated biometric sensor  610   c  and/or an input (e.g., finger contact) on biometric sensor  612   c , as shown in  FIG.  6 O . 
     At  FIG.  6 O , verification user interface  640  includes visual indicator  640   a  (e.g., textual indicator) prompting the user to authenticate an enrolled biometric feature. At  FIG.  6 O , computer system  600  detects user input  650   k  on integrated biometric sensor  610   c  (e.g., a contact of a user&#39;s thumb on integrated biometric sensor  610   c ) and/or user input  650   l  on biometric sensor  612   c  of peripheral device  602  (e.g., a contact of a user&#39;s thumb on integrated biometric sensor  612   c  of peripheral device  602 ). In response to detecting user input  650   k  and/or user input  650   l , computer system  600  compares data about a detected biometric feature (e.g., a fingerprint of a user&#39;s thumb detected via integrated biometric sensor  610   c  and/or biometric sensor  612   c ) to data about the enrolled biometric feature. When computer system  600  determines that data about the detected biometric feature corresponds to (e.g., matches and/or a threshold amount of data matches) the data about the enrolled biometric feature, computer system  600  enables peripheral device  602  to be used to authorize a secure operation at computer system  600  (e.g., via user input detected by biometric sensor  612   c ). When computer system  600  determines that data about the detected biometric feature does not correspond to (e.g., does not match and/or a threshold amount of data does not match) the data about the enrolled biometric feature, computer system  600  does not enable peripheral device  602  to be used to authorize a secure operation at computer system  600 . In addition, in some embodiments, when computer system  600  determines that data about the detected biometric feature does not correspond to (e.g., does not match and/or a threshold amount of data does not match) the data about the enrolled biometric feature, computer system  600  displays, via display  604 , an error user interface and/or a user interface prompting the user to provide and/or re-provide the authorization input. 
     After enrolling a biometric feature and/or enabling peripheral device  602  to be used to authorize a secure operation at computer system  600 , computer system  600  is configured to perform secure operations in response to detecting an authentication input (e.g., a user input that includes data about a detected biometric feature that corresponds to (e.g., matches and/or a threshold amount of data matches) data about an enrolled biometric feature) via integrated biometric sensor  610   c  and/or biometric sensor  612   c . The authentication input as described below with reference to  FIGS.  6 P and  6 Q  includes a finger contact on integrated biometric sensor  610   c  and/or biometric sensor  612   c . In some embodiments, the authentication input includes positioning a body part (e.g., a face and/or an eye) of a user associated with computer system  600  into a field of view of camera  610   d  (and/or a camera of peripheral device  602 ). In some embodiments, the authentication input includes speech of a user detected by a microphone of computer system  600  (and/or a microphone of peripheral device  602 ). 
     At  FIG.  6 P , computer system displays, via display  604 , browser user interface  642  associated with a browser application of computer system  600  (e.g., an application configured to access the Internet). Browser user interface  642  includes shopping user interface  644  (e.g., a webpage of a retailer) that enables computer system  600  to perform an electronic transaction. In response to one or more user inputs corresponding to a request to perform the electronic transaction, computer system  600  displays authentication user interface  646 . At  FIG.  6 P , authentication user interface  646  includes transaction details indicators  646   a - 646   e , which provide visual indications (e.g., textual indications) of a form of payment for the electronic transaction, price details of the electronic transaction, shipping details of the electronic transaction, and/or information of a user associated with computer system. In addition, authentication user interface  646  includes authentication indicator  646   f  that prompts a user to provide an authentication input to complete the electronic transaction. For instance, authentication indicator  646   f  includes an image of a fingerprint and/or text prompting the user to provide a finger contact at integrated biometric sensor  610   c  and/or biometric sensor  612   c.    
     At  FIG.  6 P , computer system  600  detects user input  650   m  via integrated biometric sensor  610   c  and/or biometric sensor  612   c . Because peripheral device  602  is enabled to detect user inputs for authorization of a secure operation, user input  650   m  at biometric sensor  612   c  can be detected by computer system  600  and computer system  600  can determine whether user input  650   m  includes data about a biometric feature that corresponds to data about an enrolled biometric feature (e.g., user input  650   m  at biometric sensor  612   c  can be the authentication input used to complete the electronic transaction) to authenticate the electronic transaction. Alternatively or in addition, computer system  600  can determine whether user input  650   m  at integrated biometric sensor  610   c  includes data about a biometric feature that corresponds to an enrolled biometric feature of computer system  600  to authenticate the electronic transaction. Thus, computer system  600  can receive the authentication input via integrated biometric sensor  610   c  and biometric sensor  612   c.    
     When computer system  600  determines that data about a biometric feature detected by integrated biometric sensor  610   c  and/or biometric sensor  612   c  corresponds to data about the enrolled biometric feature, computer system  600  can initiate a process for completing the electronic transaction (e.g., authenticate and/or authorize completion of the electronic transaction). When computer system  600  determines that the data about the biometric feature detected by integrated biometric sensor  610   c  and/or biometric sensor  612   c  does not correspond to data about the enrolled biometric feature, computer system forgoes initiating the process for completing (and/or completion of) the electronic transaction (e.g., and, optionally, displays an error user interface object). 
     At  FIG.  6 Q , computer system  600  displays, via display  604 , browser user interface  642  associated with a browser application of computer system  600  (e.g., an application configured to access the Internet). Browser user interface  642  includes application user interface  648  that enables computer system  600  to download and/or otherwise obtain access to a particular application and/or software program. In response to one or more user inputs corresponding to a request to download the application and/or software program, computer system  600  displays authentication user interface  652 . At  FIG.  6 Q , authentication user interface  652  includes authentication indicator  652   a  that prompts a user to provide an authentication input to initiate the process for downloading the application and/or software program. For instance, authentication indicator  652   a  includes an image of a fingerprint and/or text prompting the user to provide a finger contact at integrated biometric sensor  610   c  and/or biometric sensor  612   c . At  FIG.  6 Q , authentication user interface  652  also includes password user interface object  652   b  and cancel user interface object  652   c . In response to detecting user input corresponding to selection of password user interface object  652   b , computer system  600  enables a user to enter an alphanumeric password (e.g., via keyboard  610   a  and/or keyboard  612   a ) instead of providing the authentication input. In response to detecting user input corresponding to selection of cancel user interface object  652   c , computer system  600  ceases to display authentication user interface  652  and does not download a selected application and/or software program. 
     At  FIG.  6 Q , computer system  600  detects user input  650   n  via integrated biometric sensor  610   c  and/or biometric sensor  612   c . Because peripheral device  602  is enabled to detect user inputs for authorization of a secure operation, user input  650   n  at biometric sensor  612   c  can be detected by computer system  600  and computer system  600  can determine whether user input  650   n  includes data about a biometric feature that corresponds to data about an enrolled biometric feature (e.g., user input  650   n  at biometric sensor  612   c  can be the authentication input used to initiate downloading the application and/or software program) to authenticate downloading of the application and/or software program. Alternatively, computer system  600  can determine whether user input  650   n  at integrated biometric sensor  610   c  includes data about a biometric feature that corresponds to an enrolled biometric feature of computer system  600  to authenticate downloading the application and/or software program. Thus, computer system  600  can receive the authentication input via integrated biometric sensor  610   c  and biometric sensor  612   c.    
     When computer system  600  determines that data about a biometric feature detected by integrated biometric sensor  610   c  and/or biometric sensor  612   c  corresponds to data about the enrolled biometric feature, computer system  600  can initiate a process for downloading a selected application and/or software program. When computer system  600  determines that the data about the biometric feature detected by integrated biometric sensor  610   c  and/or biometric sensor  612   c  does not correspond to data about the enrolled biometric feature, computer system forgoes initiating the process for downloading a selected application and/or software program (e.g., and, optionally, displays an error user interface object). 
       FIGS.  6 R- 6 T  illustrate exemplary embodiments of peripheral device  602  connected to computer system  654 , which is a desktop computer. A process for enrolling a biometric feature for use by peripheral device  602  to authorize a secure operation at computer system  654  is similar to the process described above with reference to  FIGS.  6 A- 6 Q . However, because computer system  654  does not include an integrated biometric sensor (such as  610   c ), computer system  654  optionally does not enroll a biometric feature without detecting an authorization input at an input device of computer system  654  (e.g., an input device that is physically connected to, integrated into a housing of, and/or part of computer system  654 ) and/or without detecting that data about a biometric feature detected by biometric sensor  612   c  corresponds to data about an enrolled biometric feature of computer system  654 . 
     At  FIG.  6 R , peripheral device  602  is connected to computer system  654 , as represented by dashed line  656 . Dashed line  656  represents a wireless connection between peripheral device  602  and computer system  654 , such as a short-range communication connection (e.g., Bluetooth, Wi-Fi, and/or Zigbee). Computer system  654  includes display  658  and power button  660 . At  FIG.  6 R , computer system  654  displays, via display  658 , enrollment user interface  662 . In some embodiments, computer system  654  displays enrollment user interface  662  in response to detecting an established connection between computer system  654  and peripheral device  602 . In some embodiments, computer system  654  displays enrollment user interface  662  in response to one or more user inputs corresponding to a request to enroll a biometric feature. 
     Enrollment user interface  662  includes visual indicator  662   a  (e.g., textual indications) providing instructions to the user associated with computer system to perform various user inputs and/or actions to complete enrollment of the biometric feature. At  FIG.  6 R , visual indicator  662   a  prompts a user to rest their finger on biometric sensor  612   c . Further, visual indicator  662   a  prompts the user to lift and re-position (e.g., rest) their finger on biometric sensor  612   c.    
     At  FIG.  6 R , computer system  654  detects user input  650   o  via biometric sensor  612   c  of peripheral device  602 . In response to detecting user input  650   o  (and/or, optionally, as part of a setup process), computer system  654  displays verification user interface  664 , as shown at  FIG.  6 S . Because peripheral device  602  is a separate component from, and/or not integrated with, computer system  654 , computer system  654  displays verification user interface  664  to confirm that a user in possession of peripheral device  602  is the same user that is in possession of computer system  654 . Thus, by displaying verification user interface  664 , computer system  654  includes enhanced security by preventing and/or blocking a user that is not in possession of computer system  654  from enrolling a biometric feature that can be used to authorize secure operations at computer system  654  (e.g., via peripheral device  602 ). 
     For instance, at  FIG.  6 S , verification user interface  664  includes visual indicator  664   a  (e.g., textual indications) prompting a user to provide an authorization input (e.g., an authorization user input) corresponding to power button  660  of computer system  654 . Because power button  660  is integrated with (e.g., physically connected to and/or a part of) computer system  654 , detecting an input at power button  660  of computer system  654  ensures that the user enrolling the biometric feature using biometric sensor  612   c  of peripheral device  602  is in possession of (e.g., and/or in close proximity to) computer system  654 . At  FIG.  6 S , visual indicator  664   a  prompts a user to perform the authorization input by double pressing power button  660 . In some embodiments, visual indicator  664   a  can prompt the user to perform the authorization input via a single press of power button  660  and/or an input corresponding to another input device physically connected to computer system  654 . 
     At  FIG.  6 S , computer system  654  detects user input  650   p  via power button  660 . Based on a determination that user input  650   p  includes the authorization input (e.g., a double press gesture on power button  660 ), computer system  654  enables enrollment of the biometric feature detected via biometric sensor  612   c  of peripheral device  602 . In some embodiments, based on a determination that user input  650   p  does not include the authorization input (e.g., a gesture/input that is not a double press gesture on power button  660 ), computer system  654  displays, via display  658 , an error user interface (e.g., similar to error user interface  668  shown at  FIG.  6 U ). In some embodiments, based on a determination that user input  650   p  does not include the authorization input, computer system  654  maintains display of, via display  658 , verification user interface  664  and/or displays another user interface prompting a user to provide and/or re-provide the authorization input. 
     After enrolling the biometric feature (e.g., after storing data about a detected biometric feature received via biometric sensor  612   c ), computer system  654  can authorize a secure operation to be performed at computer system  654  in response to detecting an authentication input via biometric sensor  612   c . At  FIG.  6 T , computer system  654  displays locked mode user interface  666  (e.g., a lock screen of computer system  654 ). Locked mode user interface  666  includes authentication indicator  666   a  (e.g., a textual indicator) prompting a user to provide an authentication input to biometric sensor  612   c  in order to unlock computer system  654  and transition computer system  654  from a locked mode to an unlocked mode (e.g., a normal operating mode). 
     At  FIG.  6 T , computer system  654  detects user input  650   q  via biometric sensor  612   c . Because peripheral device  602  is enabled to detect user inputs for authorization of a secure operation, user input  650   q  at biometric sensor  612   c  can be detected by computer system  654  and computer system  654  can determine whether user input  650   q  includes data about a biometric feature that corresponds to data about an enrolled biometric feature (e.g., user input  650   q  at biometric sensor  612   c  can be the authentication input used to unlock computer system  654 ). 
     When computer system  654  determines that data about a biometric feature detected by biometric sensor  612   c  corresponds to data about the enrolled biometric feature, computer system  654  can initiate a process to transition from a locked mode to an unlocked mode (e.g., transition from locked mode user interface  666  to an unlocked mode user interface). When computer system  654  determines that the data about the biometric feature detected by biometric sensor  612   c  does not correspond to data about the enrolled biometric feature, computer system forgoes initiating the process to transition from the locked mode to the unlocked mode (e.g., and, optionally, displays an error user interface object). 
     As set forth above, computer system  600  and/or computer system  654  is configured to display, via display  604  and/or display  658 , error user interface  668  based on a determination that a detected user input does not include the authorization input (e.g., a double press of integrated biometric sensor  610   c , a double press of power button  660 , and/or another suitable authorization input). At  FIG.  6 U , error user interface  668  includes indicator  668   a  (e.g., a textual indicator) prompting the user to re-provide the authorization input to computer system  600  and/or computer system  654 . In some embodiments, while displaying error user interface  668 , in response to detecting the authorization input (e.g., a double press of integrated biometric sensor  610   c , a double press of power button  660 , and/or another suitable authorization input), computer system  600  displays, via display  604 , enrollment user interface  618  and/or confirmation user interface  620 . In some embodiments, in response to detecting a user input that does not include the authorization input, computer system  600  maintains display, via display  604 , of error user interface  668 . 
       FIGS.  7 A- 7 C  are a flow diagram illustrating a method for enrolling a biometric feature for use with a peripheral device using an electronic device in accordance with some embodiments. Method  700  is performed at a device (e.g.,  100 ,  300 ,  500 ,  600 , and/or  654 ) with a display generation component (e.g.,  604 ,  622 , and/or  658 ) and one or more input devices physically connected to the device (e.g.,  610   a ,  610   b ,  610   c ,  610   d , and/or  660 ). Some operations in method  700  are, optionally, combined, the orders of some operations are, optionally, changed, and some operations are, optionally, omitted. 
     As described below, method  700  provides an intuitive way for enrolling a biometric feature for use with a peripheral device. The method reduces the cognitive burden on a user for enrolling a biometric feature for use with a peripheral device, thereby creating a more efficient human-machine interface. For battery-operated computing devices, enabling a user to enrolling a biometric feature for use with a peripheral device faster and more efficiently conserves power and increases the time between battery charges. 
     A computer system (e.g.,  100 ,  300 ,  500 ,  600 , and/or  654 ) (e.g., an electronic device; a smart device, such as a smartphone or a smartwatch; a mobile device; and/or a wearable device) is in communication with a display generation component (e.g.,  604 ,  622 , and/or  658 ) and one or more input devices (e.g.,  610   a ,  610   b ,  610   c ,  610   d , and/or  660 ) physically connected to (e.g., integrated with such as by being permanently or semi-permanently mechanically and/or electrically connected to or coupled to; incorporated into and/or attached to a housing of, such as a physical, depressible button; connected via a wired connection with; connected to without requiring software that is different from (or in addition to) an operating system of the computer system; a hardware component of; connected to and positioned in close proximity to the display generation component of; a part of; and/or mechanically fastened to a housing of) the computer system (e.g., one or more input devices that are part of the computer system (e.g., integrated into a housing of the computer system) and/or connected to the computer system via a wired connection, such as a trackpad and/or mousepad, physical buttons integrated into a housing of the computer system, a touch-sensitive display, and/or a biometric sensor (e.g., a facial recognition sensor (e.g., a camera), an iris detection sensor (e.g., a camera), a fingerprint sensor, and/or a speech recognition sensor (e.g., a microphone))). 
     While the computer system is connected to (e.g., paired to via a wireless, such as Bluetooth, connection and/or connected to via a wired connection) an external device (e.g.,  602 ) (e.g., an external device configured to provide input signals to the computer system, such as an external keyboard (e.g., a keyboard that is separate from a housing of the computer system) that is not integrated with and/or physically connected to the computer system), the computer system receives ( 702 ) a first request (e.g.,  650   b ,  650   c ,  650   e ,  650   f ,  650   h ,  650   j , and/or  650   o ) (e.g., an input received by the external device and transmitted to the computer system, such as an input on a biometric sensor integrated with the external device, and/or an input received by (and at) the computer system requesting to enroll a biometric feature using the external device) to enroll a biometric feature (e.g., one or more biometric features of a user, such as one or more facial features, iris features, a fingerprint, and/or characteristics of a user&#39;s voice and/or speech) for use in authorizing a secure operation at the computer system (e.g., an operation configured to be performed by the computer system for which authorization is required) (e.g., using the computer system to authenticate a credit card and/or other form of payment to complete a transaction, using the computer system to view and/or access a protected document, and/or causing the computer system to transition between a locked and/or secure mode of operation to an unlocked and/or normal mode of operation). 
     In response to receiving ( 704 ) the first request and in accordance with a determination that the first request satisfies a first set of one or more criteria (e.g., that the first request is received and/or detected by an input device of the external device, that the external device is wirelessly connected to the computer system, and/or that the first request is received at the external device and the first request is not associated with a biometric feature already enrolled on the computer system), the first set of one or more criteria includes a first criterion that is met when data about the biometric feature that is to be enrolled is detected via a biometric sensor that is integrated with the external device (e.g.,  612   c ) (e.g., a biometric sensor that is mechanically connected to the external device, part of the external device, and/or integrated into a housing of the external device), the computer system displays ( 706 ), via the display generation component, a first user interface object (e.g.,  616 ,  626 ,  638 ,  640 , and/or  664 ) (e.g., a push notification, a pop-up window, and/or a user interface associated with the connection between the computer system and the external device) prompting a user to provide an authorization input to the computer system, via the one or more input devices (e.g.,  610   a ,  610   b ,  610   c ,  610   d , and/or  660 ) physically connected to the computer system (e.g., visual instructions (e.g., images and/or text) for the user to follow to provide a particular input that is configured to be received by the one or more input devices physically connected to the computer system and not an input to one or more additional input devices (e.g., keys and/or sensors) of the external device). 
     In some embodiments, in accordance with a determination that the first request does not satisfy the first set of one or more criteria, the computer system forgoes displaying, via the display generation component, the first user interface object prompting the user to provide the authorization input, via the one or more input devices physically connected to the computer system. In some embodiments, the computer system enrolls a biometric feature and/or initiates a process to enroll a biometric feature for the external device in accordance with the determination that the first request does not satisfy the first set of one or more criteria. In some embodiments, the computer system displays an error message in accordance with the determination that the first request does not satisfy the first set of one or more criteria. In some embodiments, the computer system continues and/or completes a set-up process for the external device so that the external device can be used with the computer system in accordance with the determination that the first request does not satisfy the first set of one or more criteria. 
     In some embodiments, the first set of one or more criteria includes a third criterion that is met when the data about the biometric feature that is to be enrolled does not correspond to (e.g., does not match and/or a threshold amount of data does not match) data about an enrolled biometric feature of the computer system. Further, in some embodiments, in response to receiving the first request and in accordance with a determination that the first request does not satisfy the first set of one or more criteria (e.g., when the data about the biometric feature that is to be enrolled corresponds to (e.g., matches and/or a threshold amount of data matches) data about an enrolled biometric feature of the computer system), the computer system enables ( 708 ) the biometric sensor that is integrated with the external device (e.g.,  612   c ) to be used to authorize secure operations at the computer system without requiring the user to provide the authorization input to the computer system (e.g., without displaying the first user interface object prompting the user to provide the authorization input to the computer system) (e.g., the biometric sensor integrated with the external device can be utilized to detect data about a biometric feature for authenticating a secure operation at the computer system without requiring the authorization input detected via the one or more input devices physically connected to the computer system). 
     Forgoing displaying the first user interface object prompting the user to provide an authorization input to the one or more input devices physically connected to the computer system when data about the biometric feature that is to be enrolled corresponds to data about an enrolled biometric feature enhances a security of the computer system by confirming that a user initiating the first request is in possession of both the computer system and the external device and reduces the number of inputs required to enable the external device to be used to authorize the secure operation at the computer system. Enhancing a security of the computer system and reducing the number of inputs needed to perform an operation enhances the operability of the device and makes the user-device interface more efficient (e.g., by helping the user to provide proper inputs and reducing user mistakes when operating/interacting with the device) which, additionally, reduces power usage and improves battery life of the device by enabling the user to use the device more quickly and efficiently. 
     While the computer system displays the first user interface object, the computer system receives ( 710 ), via the one or more input devices (e.g.,  610   a ,  610   b ,  610   c ,  610   d , and/or  660 ) physically connected to the computer system, user input (e.g.,  650   d ,  650   i ,  650   k , and/or  650   p ). 
     In response to receiving the user input ( 712 ) and in accordance with a determination that the user input includes the authorization input (e.g.,  650   d ,  650   i ,  650   k , and/or  650   p ), the computer system initiates ( 714 ) a process to enroll the biometric feature using data about the biometric feature detected via the biometric sensor that is integrated with the external device (e.g.,  612   c ) (e.g., providing an additional user interface object prompting the user to provide one or more inputs to the biometric sensor that is integrated with the external device, where the one or more inputs enable the external device and/or the computer system to confirm the data about the biometric feature detected via the biometric sensor that is integrated with the external device and/or receive data about a biometric feature associated with the user, such that the computer system and/or the external device may be utilized to receive the biometric information and authorize the computer system to perform the secure operation). In some embodiments, in response to receiving the user input and in accordance with a determination that the user input does not include the authorization input (e.g., the user input includes a different type of input than what the user interface object prompted the user to provide), the computer system does not initiate the process to enroll credentials for the external device (e.g., displays an error message, maintains display of the first user interface object prompting the user to provide the authorization input, and/or re-displays the first user interface object prompting the user to provide the authorization input). 
     Displaying the first user interface object prompting the user to provide an authorization input to the one or more input devices physically connected to the computer system enhances a security of the computer system by confirming that a user initiating the first request is in possession of both the computer system and the external device. Enhancing a security of the computer system enhances the operability of the device and makes the user-device interface more efficient (e.g., by helping the user to provide proper inputs and reducing user mistakes when operating/interacting with the device) which, additionally, reduces power usage and improves battery life of the device by enabling the user to use the device more quickly and efficiently. 
     In some embodiments, the authorization input includes an authentication user input (e.g.,  650   k ) (e.g., placing a finger on a biometric sensor of the one or more input devices physically connected to the computer system and/or adjusting a position of the user and/or the computer system to place a body part (e.g., face, eyes, and/or finger) of the user within a detectable area of a biometric sensor of the one or more input devices physically connected to the computer system) detected by the one or more input devices (e.g.,  610   c ) physically connected to the computer system (e.g., an integrated biometric sensor (e.g., fingerprint sensor) of the computer system), wherein the authentication user input includes data about a biometric feature that corresponds to (e.g., matches and/or a threshold amount of data matches) data about a previously enrolled biometric feature that was previously enrolled on the computer system (e.g., data (e.g., stored in memory of the computer system) about a fingerprint that, when detected via a biometric sensor (e.g., an integrated fingerprint sensor of the computer system), authorizes a secure operation to be performed by the computer system). 
     Receiving an authorization input at an input device that is physically connected to the computer system, such as an integrated biometric sensor of the one or more input devices that are physically connected to the computer system, enhances a security of the computer system by confirming that a user initiating the first request is in possession of both the computer system and the external device. Enhancing a security of the computer system enhances the operability of the device and makes the user-device interface more efficient (e.g., by helping the user to provide proper inputs and reducing user mistakes when operating/interacting with the device) which, additionally, reduces power usage and improves battery life of the device by enabling the user to use the device more quickly and efficiently. 
     In some embodiments, the authorization input includes user interaction (e.g.,  650   d ,  650   i ,  650   k , and/or  650   p ) (e.g., user input, such as a single press gesture, single double gesture, and/or tap gesture detected by a button and/or touch-sensitive display of the one or more input devices physically connected to the computer system, and/or movement of the user and/or the computer system that is detected by the one or more input devices physically connected to the computer system (e.g., motion sensors and/or a camera)) detected by (e.g., sensed and/or received by) an input device (e.g.,  610   a ,  610   b ,  610   c ,  610   d , and/or  660 ) of the one or more input devices physically connected to the computer system. 
     Receiving an authorization input at an input device that is physically connected to the computer system, such as a button of the one or more input devices that are physically connected to the computer system, enhances a security of the computer system by confirming that a user initiating the first request is in possession of both the computer system and the external device. Enhancing a security of the computer system enhances the operability of the device and makes the user-device interface more efficient (e.g., by helping the user to provide proper inputs and reducing user mistakes when operating/interacting with the device) which, additionally, reduces power usage and improves battery life of the device by enabling the user to use the device more quickly and efficiently. 
     In some embodiments, the input device (e.g.,  610   a ,  610   b ,  610   c ,  610   d , and/or  660 ) of the one or more input devices physically connected to the computer system is integrated into a housing (e.g.,  600   d ) of the computer system (e.g., a physical button that is incorporated into a housing of the computer system, where the housing of the computer system includes one or more components of the computer system, such as a processor, memory, and/or the display generation component, such as a power button, a volume button, or the like) (e.g., and the user interaction includes user input (e.g., a press gesture and/or a tap gesture) detected by the input device integrated into the housing of the computer system). 
     Receiving an authorization input at an input device that is physically connected to the computer system, such as a button of the one or more input devices that are physically connected to the computer system, enhances a security of the computer system by confirming that a user initiating the first request is in possession of both the computer system and the external device. Enhancing a security of the computer system enhances the operability of the device and makes the user-device interface more efficient (e.g., by helping the user to provide proper inputs and reducing user mistakes when operating/interacting with the device) which, additionally, reduces power usage and improves battery life of the device by enabling the user to use the device more quickly and efficiently. 
     In some embodiments, the input device of the one or more input devices physically connected to the computer system is a button (e.g.,  610   c  and/or  660 ) (e.g., a physical, depressible button that is integrated into a housing of the computer system) (e.g., and the user interaction includes user input (e.g., a press gesture on the button and/or a depression of the button) corresponding to an interaction with the button). 
     The input device being a button enables the computer system to detect the authorization input as a specific input to a specific input device, such that the authorization input is not unintentionally detected via a non-physical user input (e.g., a voice input), thereby improving security of the computer system. Enhancing a security of the computer system enhances the operability of the device and makes the user-device interface more efficient (e.g., by helping the user to provide proper inputs and reducing user mistakes when operating/interacting with the device) which, additionally, reduces power usage and improves battery life of the device by enabling the user to use the device more quickly and efficiently. 
     In some embodiments, the input device of the one or more input devices physically connected to the computer system is a button (e.g.,  610   c  and/or  660 ) (e.g., a physical, depressible button that is integrated into a housing of the computer system), and wherein the user interaction includes a double press gesture (e.g.,  650   d ,  650   i , and/or  650   p ) (e.g., two presses of the second button that occur within a predefined amount of time, such as within 0.05 seconds, 0.1 seconds, 0.2 seconds, 0.3 seconds, 0.5 seconds, 1 second, 2 seconds, 3 seconds, 4 seconds, and/or 5 seconds of one another) of the button (e.g.,  610   c  and/or  660 ). 
     The authorization input including a double press gesture of a button further improves security of the computer system because the computer system does not recognize merely any input to the button as the authorization input. Enhancing a security of the computer system enhances the operability of the device and makes the user-device interface more efficient (e.g., by helping the user to provide proper inputs and reducing user mistakes when operating/interacting with the device) which, additionally, reduces power usage and improves battery life of the device by enabling the user to use the device more quickly and efficiently. 
     In some embodiments, the input device of the one or more input devices physically connected to the computer system is a power button (e.g.,  610   c  and/or  660 ) (e.g., a physical, depressible button that is integrated into a housing of the computer system and is configured to adjust and/or control an on/off setting of the computer system and/or configured to control a power supply to one or more components of the computer system) (e.g., and the user interaction includes user input (e.g., a press gesture, a tap gesture, and/or a depression of the power button) corresponding to an interaction with the power button). In some embodiments, the user input does not cause the computer system to adjust and/or control an off/setting of the computer system and/or to change a power supply to one or more components of the computer system. In some embodiments, the user input is detected as the authorization input and does not change an operating mode of the computer system, does not put the computer system into a sleep and/or idle mode, does not take the computer system out of a sleep and/or idle mode, does not turn off the computer system, and/or does not turn on the computer system. In some embodiments, the computer system is configured to change an operating mode (e.g., cause the computer system to operate in a sleep and/or idle mode, cause the computer system to transition out of the sleep and/or idle mode, cause the computer system to turn off, and/or cause the computer system to turn on) in response to detecting a user input that is different from the authorization input, such as a long press gesture detected at the power button. 
     Receiving an authorization input at a power button enhances a security of the computer system by using an input device that is not frequently interacted with by a user during normal operation of the computer system, and thus, a user is unlikely to inadvertently provide a user input to the power button and unintentionally provide the authentication input. Enhancing a security of the computer system enhances the operability of the device and makes the user-device interface more efficient (e.g., by helping the user to provide proper inputs and reducing user mistakes when operating/interacting with the device) which, additionally, reduces power usage and improves battery life of the device by enabling the user to use the device more quickly and efficiently. 
     In some embodiments, the input device of the one or more input devices physically connected to the computer system is a button (e.g., a physical, depressible button incorporated into a housing of the computer system) having an integrated biometric sensor (e.g.,  610   c ) (e.g., in addition to being a physical, depressible button, the third button includes one or more sensors that are configured to detect and/or sense a biometric feature of a user, such as a fingerprint, vein pattern, heart rate, facial features, iris features, and/or speech characteristics) (e.g., and the user interaction includes user input (e.g., a press gesture, a tap gesture, placement of a finger on the third button, movement of the user in front of the biometric sensor, and/or speech of a user) corresponding to an interaction with the third button having the integrated biometric sensor). 
     Receiving an authorization input at a button having an integrated biometric sensor enhances a security of the computer system because the integrated biometric sensor can optionally be used to provide further confirmation that the user providing the authorization input is a user associated with the computer system. Enhancing a security of the computer system enhances the operability of the device and makes the user-device interface more efficient (e.g., by helping the user to provide proper inputs and reducing user mistakes when operating/interacting with the device) which, additionally, reduces power usage and improves battery life of the device by enabling the user to use the device more quickly and efficiently. 
     In some embodiments, the first set of one or more criteria includes a second criterion that is met when the data about the biometric feature that is to be enrolled does not correspond to (e.g., does not match and/or a threshold amount of data does not match) data about an enrolled biometric feature (e.g., data about a biometric feature of a user of the computer system that is stored in memory of the computer system and is compared to data about a biometric feature detected via an authorized biometric sensor (e.g., the biometric sensor integrated with the external device and/or a biometric sensor of the one or more input devices physically connected to the computer system) to authorize a secure operation at the computer system) of the computer system (e.g., the computer system displays the prompt in response to receiving a request that includes data about the biometric feature that is to be enrolled and that is detected via a biometric sensor that is integrated with the external device and in accordance with a determination that the data about the biometric feature detected by the biometric sensor that is integrated with the external device does not match data about an enrolled biometric feature). In some embodiments, the data about the biometric feature that is to be enrolled and that is detected via the biometric sensor integrated with the external device is enrolled in response to receiving the user input that includes the authorization input. In some embodiments, the data about the biometric feature that is to be enrolled and that is detected via the biometric sensor integrated with the external device is enrolled, such that data about a biometric feature that is detected via the biometric sensor integrated with the external device and/or a biometric sensor of the one or more input devices physically connected to the computer system is used to authenticate a secure operation at the computer system. 
     Displaying the first user interface prompting the user to provide the authorization input indicates to the user that the external device needs to be authenticated, thereby improving security of the computer system. Enhancing a security of the computer system enhances the operability of the device and makes the user-device interface more efficient (e.g., by helping the user to provide proper inputs and reducing user mistakes when operating/interacting with the device) which, additionally, reduces power usage and improves battery life of the device by enabling the user to use the device more quickly and efficiently. 
     In some embodiments, prior to the computer system receiving the first request and in accordance with a determination that an integrated biometric sensor (e.g.,  610   c ) of the one or more input devices physically connected to the computer system (e.g., a biometric sensor that is integrated with and/or incorporated into a housing of the computer system) is available (e.g., the computer system operates in a first mode of operation (e.g., a foldable lid of the computer system is in an open position), the computer system includes an integrated biometric sensor that is available for selection (e.g., not covered by the foldable lid of the computer system), and/or the computer system includes a connection with (e.g., an established connection with) a biometric sensor different from the biometric sensor that is integrated with the external device), the computer system collects biometric information for the user with the integrated biometric sensor (e.g.,  610   c ) of the one or more input devices physically connected to the computer system (e.g., without collecting biometric information for the user with the biometric sensor that is integrated with the external device). In addition, prior to the computer system receiving the first request and in accordance with a determination that the integrated biometric sensor (e.g.,  610   c ) of the one or more input devices physically connected to the computer system is not available (e.g., the computer system operates in a second mode of operation (e.g., a foldable lid of the computer system is in a closed position), different from the first mode of operation, the computer system does not include an integrated biometric sensor, and/or the computer system does not include a connection with (e.g., an established connection with) a biometric sensor different from the biometric sensor that is integrated with the external device), the computer system collects biometric information for the user with the biometric sensor that is integrated with the eternal device (e.g.,  612   c ) (e.g., without collecting biometric information for the user with the integrated biometric sensor of the one or more input devices physically connected to the computer system). 
     Enabling the integrated biometric sensor of the one or more input devices physically connected to the computer system to read biometric information when the integrated biometric sensor is available reduces the number of inputs required to enable the external device to be used to authorize the secure operation at the computer system because the computer system does not receive the authorization input before initiating the process to enroll the biometric feature. Reducing the number of inputs needed to perform an operation enhances the operability of the device and makes the user-device interface more efficient (e.g., by helping the user to provide proper inputs and reducing user mistakes when operating/interacting with the device) which, additionally, reduces power usage and improves battery life of the device by enabling the user to use the device more quickly and efficiently. 
     In some embodiments, the integrated biometric sensor (e.g.,  610   c ) of the one or more input devices physically connected to the computer system is not available when the computer system is a notebook computer (e.g.,  600 ) (e.g., a laptop computer having a foldable lid (e.g., a first portion of a housing of the computer system that is connected to a second portion of the housing of the computer system with a hinge or other flexible connection)) having an integrated display (e.g.,  604 ) (e.g., the display generation component is integrated with and/or incorporated into the foldable lid (e.g., the first portion of the housing of the computer system)) and the integrated display is closed (e.g., the integrated display and/or the foldable lid is in a closed position (e.g., the integrated biometric sensor of the one or more input devices physically connected to the computer system is blocked and/or obstructed via the integrated display and/or the foldable lid) and/or the computer system is operating in a clamshell mode). In some embodiments (e.g., in the clamshell mode), the computer system is connected to an external display that displays content while the integrated display of the computer system is closed and does not display content. 
     The integrated sensor being unavailable when the integrated display is closed allows the computer system to monitor for inputs at input devices are available and to not monitor for inputs at input devices that are not available, thereby reducing the power required to monitor for inputs, such as the authorization input. Reducing the power required to perform an operation enhances the operability of the device and makes the user-device interface more efficient (e.g., by helping the user to provide proper inputs and reducing user mistakes when operating/interacting with the device) which, additionally, reduces power usage and improves battery life of the device by enabling the user to use the device more quickly and efficiently. 
     In some embodiments, the integrated biometric sensor (e.g.,  610   c ) of the one or more input devices physically connected to the computer system is available when the computer system is the notebook computer (e.g.,  600 ) (e.g., a laptop computer having a foldable lid (e.g., a first portion of a housing of the computer system that is connected to a second portion of the housing of the computer system via a hinge or other flexible connector)) having the integrated display (e.g.,  604 ) (e.g., the display generation component is integrated with and/or incorporated into the foldable lid (e.g., the first portion of the housing of the computer system)) and the integrated display is open (e.g., the integrated display and/or the foldable lid is in an open position (e.g., the integrated biometric sensor of the one or more input devices physically connected to the computer system is not blocked and/or obstructed via the integrated display and/or the foldable lid) and/or the computer system is not operating in a clamshell mode). 
     The integrated sensor being available when the integrated display is open allows the computer system to monitor for inputs at input devices are available and to not monitor for inputs at input devices that are not available, thereby reducing the power required to monitor for inputs, such as the authorization input. Reducing the power required to perform an operation enhances the operability of the device and makes the user-device interface more efficient (e.g., by helping the user to provide proper inputs and reducing user mistakes when operating/interacting with the device) which, additionally, reduces power usage and improves battery life of the device by enabling the user to use the device more quickly and efficiently. 
     In some embodiments, in response to the computer system receiving the first request and in accordance with a determination that the first request satisfies a second set of one or more criteria, the second set of one or more criteria including a fourth criterion that is met when data about the biometric feature that is to be enrolled is detected via an integrated biometric sensor (e.g.,  610   c ) of the one or more input devices physically connected to the computer system e.g., a biometric sensor that is integrated with and/or incorporated into a housing of the computer system instead of the biometric sensor that is integrated with the external device), the computer system initiates a process to enroll the biometric feature for use in authorizing the secure operation at the computer system via an authenticated input (e.g.,  650   m ,  650   n , and/or  650   q ) (e.g., an input that that includes data about the enrolled biometric feature detected via the biometric sensor that is integrated with the external device and/or via the integrated biometric sensor of the one or more input devices physically connected to the computer system). In some embodiments, the second set of one or more criteria includes a criterion that is met when the computer system does not include an enrolled biometric feature. 
     Enabling enrollment of a biometric feature via the integrated biometric sensor of the one or more input devices physically connected to the computer system improves security of the computer system by enrolling a biometric feature via an input that is detected at an input device of the computer system. Enhancing a security of the computer system enhances the operability of the device and makes the user-device interface more efficient (e.g., by helping the user to provide proper inputs and reducing user mistakes when operating/interacting with the device) which, additionally, reduces power usage and improves battery life of the device by enabling the user to use the device more quickly and efficiently. 
     In some embodiments, prior to connecting the external device (e.g.,  602 ) to the computer system (e.g., and prior to receiving the first request), the computer system receives a second request to connect (e.g., pair) the external device to the computer system (e.g., user input corresponding to a request to search for one or more external devices via a wireless connection (e.g., Bluetooth, Wi-Fi, and/or Zigbee) and/or detecting a wired connection between the external device and the computer system). In response to receiving the second request and in accordance with a determination that the computer system is not associated with an enrolled biometric feature (e.g., the computer system does not include (e.g., has not received) data about a biometric feature stored in memory of the computer system and/or in memory accessible to the computer system (e.g., memory of a server associated with an account of a user associated with the computer system), where the enrolled biometric feature includes data corresponding to a biometric feature of a user associated with the computer system), the computer system initiates a process to connect the external device to the computer system (e.g., establishing a wireless and/or wired connection between the external device and the computer system) and displays a third user interface object (e.g.,  634 ,  636 ,  638 , and/or  640 ) prompting the user to provide an enrollment input (e.g., visual instructions (e.g., images and/or text) for the user to follow to provide one or more particular inputs that are configured to be received by the one or more input devices physically connected to the computer system and/or configured to be received by the biometric sensor that is integrated with the external device). In response to receiving the second request and in accordance with a determination that the computer system is associated with an enrolled biometric feature (e.g., the computer system includes (e.g., has received) data about a biometric feature stored in memory of the computer system and/or in memory accessible to the computer system (e.g., memory of a server associated with an account of a user associated with the computer system), where the enrolled biometric feature includes data corresponding to a biometric feature of a user associated with the computer system), the computer system initiates a process to connect the external device to the computer system without displaying the third user interface object (e.g.,  634 ,  636 ,  638 , and/or  640 ) prompting the user to provide the enrollment input (e.g., a wireless and/or wired connection between the external device and the computer system is established without displaying a visual indication instructing a user to provide one or more inputs to enroll a biometric feature). 
     Initiating the process to connect the external device to the computer system when the computer system includes an enrolled biometric feature enables the computer system to utilize the enrolled biometric feature as the authentication input and/or as further confirmation that the authentication input is valid (e.g., via fingerprint matching), thereby increasing a security of the computer system. Displaying the third user interface prompting the user to provide the enrollment input when the computer system does not include an enrolled biometric feature enables the computer system to include an enrolled biometric feature for authorizing secure operations at the computer system, thereby increasing a security of the computer system. Enhancing a security of the computer system enhances the operability of the device and makes the user-device interface more efficient (e.g., by helping the user to provide proper inputs and reducing user mistakes when operating/interacting with the device) which, additionally, reduces power usage and improves battery life of the device by enabling the user to use the device more quickly and efficiently. 
     In some embodiments, the second request to connect the external device (e.g.,  602 ) to the computer system includes initiating a process to connect the external device to the computer system via a short-range communication protocol (e.g., Bluetooth, a personal area network) (e.g., initiating the process to connect the external device to the computer system via a settings user interface of the computer system, a Bluetooth settings user interface of the computer system, and/or a keyboard settings user interface of the computer system). 
     Displaying the first user interface prompting the user to provide the authorization input when the external device and the computer system are connected via short-range protocol improves a security of the computer system because an unauthorized user may attempt to connect an unauthorized external device to the computer system via the short-range communication connection. Enhancing a security of the computer system enhances the operability of the device and makes the user-device interface more efficient (e.g., by helping the user to provide proper inputs and reducing user mistakes when operating/interacting with the device) which, additionally, reduces power usage and improves battery life of the device by enabling the user to use the device more quickly and efficiently. 
     In some embodiments, in response to receiving the first request and in accordance with a determination that the external device is in wired communication (e.g., via cable  628 ) with the computer system (e.g., the computer system detects an electrical connection between the external device and the computer system based on a user inserting a connection cable into a reception port of the computer system) (e.g., the first set of one or more criteria include a criterion that is not met when the external device is in wired communication with the computer system (e.g., the external device is connected to and/or in communication with the external device via a cable)), the computer system enables the biometric sensor that is integrated with the external device (e.g.,  612   c ) to be used to authorize secure operations at the computer system without requiring the user to provide the authorization input (e.g.,  650   d ,  650   i ,  650   k , and/or  650   p ) to the computer system (e.g., without displaying the first user interface object prompting the user to provide the authorization input to the computer system) (e.g., the biometric sensor that is integrated with the external device is configured to detect and/or receive data about a biometric feature and use the data to authorize a secure operation at the computer system without requiring the authorization input). 
     Forgoing displaying the first user interface object prompting the user to provide an authorization input to the one or more input devices physically connected to the computer system when the external device is in wired communication with the computer system enhances a security of the computer system by confirming that a user initiating the first request is in possession of both the computer system and the external device and reduces the number of inputs required to enable the external device to be used to authorize the secure operation at the computer system. Enhancing a security of the computer system and reducing the number of inputs needed to perform an operation enhances the operability of the device and makes the user-device interface more efficient (e.g., by helping the user to provide proper inputs and reducing user mistakes when operating/interacting with the device) which, additionally, reduces power usage and improves battery life of the device by enabling the user to use the device more quickly and efficiently. 
     In some embodiments, the biometric sensor that is integrated with the external device (e.g.,  612   c ) (e.g., and/or the integrated biometric sensor of the one or more input devices physically connected to the computer system) is selected from the group consisting of: a fingerprint sensor (e.g., an optical sensor, a capacitance sensor, an ultrasonic sensor, and/or a thermal sensor), a face detection sensor (e.g., a camera), and an iris detection sensor (e.g., a camera). 
     Using a fingerprint sensor, a face detection sensor, or an iris detection sensor improves a security of the computer system by authorizing secure operations at the computer system via a secure sensor that identifies unique features of an authorized user of the computer system. Enhancing a security of the computer system enhances the operability of the device and makes the user-device interface more efficient (e.g., by helping the user to provide proper inputs and reducing user mistakes when operating/interacting with the device) which, additionally, reduces power usage and improves battery life of the device by enabling the user to use the device more quickly and efficiently. 
     In some embodiments, after enrolling one or more biometric features with the computer system (e.g., using data about the biometric feature detected using either the biometric sensor that is integrated with the external device or the biometric sensor that is integrated with the external device), the computer system receives ( 716 ) a third request (e.g.,  650   m ,  650   n , and/or  650   q ) to authenticate a secure operation at the computer system that includes detecting first information about a biometric feature using the biometric sensor that is integrated with the external device (e.g.,  612   c ) (e.g., detecting, via the biometric sensor that is integrated with the external device a user input that includes data about a biometric feature). 
     In response to receiving the third request ( 718 ) and in accordance with a determination that the first information is consistent with a biometric feature enrolled with the computer system (e.g., the data about the biometric feature that is detected via the biometric sensor that is integrated with the external device matches the data about the enrolled biometric feature and/or at least a threshold amount of the data about the biometric feature that is detected via the biometric sensor that is integrated with the external device matches the data about the enrolled biometric feature), the computer system initiates ( 720 ) a process to perform the secure operation at the computer system (e.g., authorization to complete a transaction, authorization to provide access a protected document, and/or authorization to cause the computer system to transition between a locked and/or secure mode of operation to an unlocked and/or normal mode of operation). 
     In response to receiving the third request ( 718 ) and in accordance with a determination that the first information is not consistent with the one or more biometric features enrolled with the computer system (e.g., the data about the biometric feature that is detected via the biometric sensor that is integrated with the external device does not match the data about the one or more enrolled biometric features and/or at least a threshold amount of the data about the biometric feature that is detected via the biometric sensor that is integrated with the external device does not match the data about the one or more enrolled biometric sensors), the computer system forgoes ( 722 ) initiating the process to perform the secure operation at the computer system (e.g., blocking completion of the secure operation at the computer system and/or displaying an error notification (e.g., a visual indication prompting the user to perform the third request again and/or prompting the user to authorize the secure operation in another manner, such as entering a password)). In some embodiments, the one or more biometric features enrolled with the computer system correspond to an account of a particular user of the computer system. For example, the computer system can include enrolled biometric features that are associated with a variety of different user accounts. When a particular user account is active (e.g., the computer system is logged into a particular user account and/or the computer system is attempting to perform the secure operation with a particular user account), the computer system determines whether the first information about the biometric feature is consistent with enrolled biometric features corresponding to the active user account. In other words, the computer system determines that the first information is not consistent with the one or more biometric features enrolled with the computer system when the first information is consistent with an enrolled biometric feature that corresponds to a user account that is not the active user account (e.g., a user account that is not being used to perform the secure operation and/or a user account that the computer system is not logged into). 
     Using the enrolled biometric feature to authorize a secure operation at the computer system enhances a security of the computer system by confirming that a user requesting performance of the secure operation is an authorized user of the computer system. Enhancing a security of the computer system enhances the operability of the device and makes the user-device interface more efficient (e.g., by helping the user to provide proper inputs and reducing user mistakes when operating/interacting with the device) which, additionally, reduces power usage and improves battery life of the device by enabling the user to use the device more quickly and efficiently. 
     In some embodiments, after enrolling one or more biometric features (e.g., using data about the biometric feature detected using either the biometric sensor that is integrated with the external device via the biometric sensor that is integrated with the external device), the computer system receives ( 724 ) a fourth request (e.g.,  650   m  and/or  650   n ) to authenticate a secure operation at the computer system that includes detecting second information about a biometric feature using an integrated biometric sensor (e.g.,  610   c ) of the one or more input devices physically connected to the computer system (e.g., detecting, via integrated biometric sensor of the one or more input devices physically connected to the computer system, a user input that includes data about a biometric feature). 
     In response to receiving the fourth request ( 726 ) and in accordance with a determination that the second information is consistent with a biometric feature enrolled with the computer system (e.g., the data about the biometric feature that is detected via the integrated biometric sensor of the one or more input devices physically connected to the computer system matches the data about the enrolled biometric feature and/or at least a threshold amount of the data about the biometric feature that is detected via the integrated biometric sensor of the one or more input devices physically connected to the computer system matches the data about the enrolled biometric feature), the computer system initiates ( 728 ) a process to perform the secure operation at the computer system (e.g., authorization to complete a transaction, authorization to provide access a protected document, and/or authorization to cause the computer system to transition between a locked and/or secure mode of operation to an unlocked and/or normal mode of operation). 
     In response to receiving the fourth request ( 726 ) and in accordance with a determination that the second information is not consistent with the one or more biometric features enrolled with the computer system (e.g., the data about the biometric feature that is detected via the integrated biometric sensor of the one or more input devices physically connected to the computer system does not match the data about the one or more enrolled biometric features and/or at least a threshold amount of the data about the biometric feature that is detected via the integrated biometric sensor of the one or more input devices physically connected to the computer system does not match the data about the one or more enrolled biometric sensors), the computer system forgoes ( 730 ) initiating the process to perform the secure operation at the computer system (e.g., blocking completion of the secure operation at the computer system and/or displaying an error notification (e.g., a visual indication prompting the user to perform the third request again and/or prompting the user to authorize the secure operation in another manner, such as entering a password)). In some embodiments, the one or more biometric features enrolled with the computer system correspond to an account of a particular user of the computer system. For example, the computer system can include enrolled biometric features that are associated with a variety of different user accounts. When a particular user account is active (e.g., the computer system is logged into a particular user account and/or the computer system is attempting to perform the secure operation with a particular user account), the computer system determines whether the first information about the biometric feature is consistent with enrolled biometric features corresponding to the active user account. In other words, the computer system determines that the first information is not consistent with the one or more biometric features enrolled with the computer system when the first information is consistent with an enrolled biometric feature that corresponds to a user account that is not the active user account (e.g., a user account that is not being used to perform the secure operation and/or a user account that the computer system is not logged into). 
     Using the enrolled biometric feature to authorize a secure operation at the computer system enhances a security of the computer system by confirming that a user requesting performance of the secure operation is an authorized user of the computer system. Enhancing a security of the computer system enhances the operability of the device and makes the user-device interface more efficient (e.g., by helping the user to provide proper inputs and reducing user mistakes when operating/interacting with the device) which, additionally, reduces power usage and improves battery life of the device by enabling the user to use the device more quickly and efficiently. 
     The foregoing description, for purpose of explanation, has been described with reference to specific embodiments. However, the illustrative discussions above are not intended to be exhaustive or to limit the invention to the precise forms disclosed. Many modifications and variations are possible in view of the above teachings. The embodiments were chosen and described in order to best explain the principles of the techniques and their practical applications. Others skilled in the art are thereby enabled to best utilize the techniques and various embodiments with various modifications as are suited to the particular use contemplated. 
     Although the disclosure and examples have been fully described with reference to the accompanying drawings, it is to be noted that various changes and modifications will become apparent to those skilled in the art. Such changes and modifications are to be understood as being included within the scope of the disclosure and examples as defined by the claims. 
     As described above, one aspect of the present technology is the gathering and use of data available from various sources to facilitate a user&#39;s ability to authorize a secure operation at a computer system. The present disclosure contemplates that in some instances, this gathered data may include personal information data that uniquely identifies or can be used to contact or locate a specific person. Such personal information data can include demographic data, location-based data, telephone numbers, email addresses, twitter IDs, home addresses, data or records relating to a user&#39;s health or level of fitness (e.g., vital signs measurements, medication information, exercise information), biometric information, date of birth, or any other identifying or personal information. 
     The present disclosure recognizes that the use of such personal information data, in the present technology, can be used to the benefit of users. For example, the personal information data can be used to facilitate authorization of a secure transaction at a computer system. 
     The present disclosure contemplates that the entities responsible for the collection, analysis, disclosure, transfer, storage, or other use of such personal information data will comply with well-established privacy policies and/or privacy practices. In particular, such entities should implement and consistently use privacy policies and practices that are generally recognized as meeting or exceeding industry or governmental requirements for maintaining personal information data private and secure. Such policies should be easily accessible by users, and should be updated as the collection and/or use of data changes. Personal information from users should be collected for legitimate and reasonable uses of the entity and not shared or sold outside of those legitimate uses. Further, such collection/sharing should occur after receiving the informed consent of the users. Additionally, such entities should consider taking any needed steps for safeguarding and securing access to such personal information data and ensuring that others with access to the personal information data adhere to their privacy policies and procedures. Further, such entities can subject themselves to evaluation by third parties to certify their adherence to widely accepted privacy policies and practices. In addition, policies and practices should be adapted for the particular types of personal information data being collected and/or accessed and adapted to applicable laws and standards, including jurisdiction-specific considerations. For instance, in the US, collection of or access to certain health data may be governed by federal and/or state laws, such as the Health Insurance Portability and Accountability Act (HIPAA); whereas health data in other countries may be subject to other regulations and policies and should be handled accordingly. Hence different privacy practices should be maintained for different personal data types in each country. 
     Despite the foregoing, the present disclosure also contemplates embodiments in which users selectively block the use of, or access to, personal information data. That is, the present disclosure contemplates that hardware and/or software elements can be provided to prevent or block access to such personal information data. For example, in the case of enrolling biometric features, the present technology can be configured to allow users to select to “opt in” or “opt out” of participation in the collection of personal information data during registration for services or anytime thereafter. In addition to providing “opt in” and “opt out” options, the present disclosure contemplates providing notifications relating to the access or use of personal information. For instance, a user may be notified upon downloading an app that their personal information data will be accessed and then reminded again just before personal information data is accessed by the app. 
     Moreover, it is the intent of the present disclosure that personal information data should be managed and handled in a way to minimize risks of unintentional or unauthorized access or use. Risk can be minimized by limiting the collection of data and deleting data once it is no longer needed. In addition, and when applicable, including in certain health related applications, data de-identification can be used to protect a user&#39;s privacy. De-identification may be facilitated, when appropriate, by removing specific identifiers (e.g., date of birth, etc.), controlling the amount or specificity of data stored (e.g., collecting location data a city level rather than at an address level), controlling how data is stored (e.g., aggregating data across users), and/or other methods. 
     Therefore, although the present disclosure broadly covers use of personal information data to implement one or more various disclosed embodiments, the present disclosure also contemplates that the various embodiments can also be implemented without the need for accessing such personal information data. That is, the various embodiments of the present technology are not rendered inoperable due to the lack of all or a portion of such personal information data. For example, a user can choose to limit credentials for authorizing a secure operation at a computer system to non-personal information data or a bare minimum amount of personal information, such as the content being requested by the device associated with a user, other non-personal information, or publicly available information.
