An electronic device comprising: a touchscreen display; a fingerprint sensor adjacent the touchscreen display; and one or more processors associated with processor-executable instructions, at least one of the processors being coupled with the touchscreen display and at least one of the processors being coupled with the fingerprint sensor, the instructions including: gesture recognition instructions associated with one or more of the processors that is coupled with the touchscreen display, the gesture recognition instructions being configured to cause that processor to detect a gesture that is characterized by input representing movement that is directed at or from the fingerprint sensor, the input being received, at least in part, at an end of the touchscreen display that is nearest the fingerprint sensor, the gesture being a command to display particular content on the touchscreen display; fingerprint acquisition instructions associated with one or more of the processors that is coupled with the fingerprint sensor, the fingerprint acquisition instructions being configured to cause that processor to obtain a fingerprint sample from the fingerprint sensor; and fingerprint authentication instructions associated with one or more of the processors, the fingerprint authentication instructions being configured to cause that processor to authenticate a user based on the fingerprint sample obtained from the fingerprint sensor, wherein one or more of the processors are further associated with instructions that cause one or more of the processors to perform at least one function apart from authentication of the fingerprint sample in response to detecting the gesture, the function involving displaying the particular content on the touchscreen display; wherein the fingerprint sensor is positioned (i) in the path of a gesture associated with a function that is not related to authentication and (ii) within one millimeter of the touchscreen display such that the gesture may cause incidental contact with the fingerprint sensor to allow the fingerprint sample to be captured passively while other things are done on the electronic device. a touchscreen display; a fingerprint sensor adjacent the touchscreen display; and one or more processors associated with processor-executable instructions, at least one of the processors being coupled with the touchscreen display and at least one of the processors being coupled with the fingerprint sensor, the instructions including: gesture recognition instructions associated with one or more of the processors that is coupled with the touchscreen display, the gesture recognition instructions being configured to cause that processor to detect a gesture that is characterized by input representing movement that is directed at or from the fingerprint sensor, the input being received, at least in part, at an end of the touchscreen display that is nearest the fingerprint sensor, the gesture being a command to display particular content on the touchscreen display; fingerprint acquisition instructions associated with one or more of the processors that is coupled with the fingerprint sensor, the fingerprint acquisition instructions being configured to cause that processor to obtain a fingerprint sample from the fingerprint sensor; and fingerprint authentication instructions associated with one or more of the processors, the fingerprint authentication instructions being configured to cause that processor to authenticate a user based on the fingerprint sample obtained from the fingerprint sensor, gesture recognition instructions associated with one or more of the processors that is coupled with the touchscreen display, the gesture recognition instructions being configured to cause that processor to detect a gesture that is characterized by input representing movement that is directed at or from the fingerprint sensor, the input being received, at least in part, at an end of the touchscreen display that is nearest the fingerprint sensor, the gesture being a command to display particular content on the touchscreen display; fingerprint acquisition instructions associated with one or more of the processors that is coupled with the fingerprint sensor, the fingerprint acquisition instructions being configured to cause that processor to obtain a fingerprint sample from the fingerprint sensor; and fingerprint authentication instructions associated with one or more of the processors, the fingerprint authentication instructions being configured to cause that processor to authenticate a user based on the fingerprint sample obtained from the fingerprint sensor,
