A method for initiating a process to receive biometric information, comprising: at an electronic device with a display, one or more input devices including a first input device, a housing, a first biometric sensor, and a second biometric sensor: receiving first biometric information from a first biometric sensor of the plurality of biometric sensors wherein the first biometric sensor is enclosed in the housing; in response to receiving the first biometric information and in accordance with a determination that the first biometric information satisfies first criteria, displaying, on the display, an alert including a first user-interactive graphical user interface object for detecting additional biometric information and a second user-interactive graphical user interface object; receiving, via the one or more input devices, a first user input; in accordance with a determination that the first user input corresponds to user activation of the first user-interactive graphical user interface object: initiating a process to receive, subsequent to receiving the user activation of the first user-interactive graphical user interface object, second biometric information associated with the first biometric information from the second biometric sensor of the plurality of biometric sensors that is different from the first biometric sensor, wherein: the second biometric sensor includes one or more electrodes integrated in the first input device, and initiating the process to receive the second biometric information includes displaying, on the display, a user interface of a first application associated with receiving the second biometric information while displaying the user interface of the first application, receiving a second user input directed to the first input device; and in response to receiving the second user input directed to the first input device, receiving the second biometric information using the second biometric sensor; and in accordance with a determination that the first user input corresponds to user activation of the second user-interactive graphical user interface object: forgoing receiving the second biometric information associated with the first biometric information from the second biometric sensor of the plurality of biometric sensors. receiving first biometric information from a first biometric sensor of the plurality of biometric sensors wherein the first biometric sensor is enclosed in the housing; in response to receiving the first biometric information and in accordance with a determination that the first biometric information satisfies first criteria, displaying, on the display, an alert including a first user-interactive graphical user interface object for detecting additional biometric information and a second user-interactive graphical user interface object; receiving, via the one or more input devices, a first user input; in accordance with a determination that the first user input corresponds to user activation of the first user-interactive graphical user interface object: initiating a process to receive, subsequent to receiving the user activation of the first user-interactive graphical user interface object, second biometric information associated with the first biometric information from the second biometric sensor of the plurality of biometric sensors that is different from the first biometric sensor, wherein: the second biometric sensor includes one or more electrodes integrated in the first input device, and initiating the process to receive the second biometric information includes displaying, on the display, a user interface of a first application associated with receiving the second biometric information while displaying the user interface of the first application, receiving a second user input directed to the first input device; and in response to receiving the second user input directed to the first input device, receiving the second biometric information using the second biometric sensor; and initiating a process to receive, subsequent to receiving the user activation of the first user-interactive graphical user interface object, second biometric information associated with the first biometric information from the second biometric sensor of the plurality of biometric sensors that is different from the first biometric sensor, wherein: the second biometric sensor includes one or more electrodes integrated in the first input device, and initiating the process to receive the second biometric information includes displaying, on the display, a user interface of a first application associated with receiving the second biometric information the second biometric sensor includes one or more electrodes integrated in the first input device, and initiating the process to receive the second biometric information includes displaying, on the display, a user interface of a first application associated with receiving the second biometric information while displaying the user interface of the first application, receiving a second user input directed to the first input device; and in response to receiving the second user input directed to the first input device, receiving the second biometric information using the second biometric sensor; and in accordance with a determination that the first user input corresponds to user activation of the second user-interactive graphical user interface object: forgoing receiving the second biometric information associated with the first biometric information from the second biometric sensor of the plurality of biometric sensors.
