Devices, methods, and graphical user interfaces for providing a home button replacement

A computer system, comprising:

• a display;
• an input mechanism;
• one or more processors;
• memory;
• and
• one or more programs, wherein the one or more programs are stored in the memory and configured to be executed by the one or more processors, the one or more programs including instructions for:
• displaying a first user interface on the display that corresponds to a locked state of the computer system;
• while displaying the first user interface, detecting, via the input mechanism, a first user input;
• and
• in response to detecting the first user input via the input mechanism:
• in accordance with a determination that the first user input includes a first type of interaction with the input mechanism and that the first user input meets fingerprint authentication criteria, replacing display of the first user interface with display of a second user interface that is different from the first user interface, wherein the second user interface is a most recently displayed user interface that was displayed before the computer system entered the locked state;
• and
• in accordance with a determination that the first user input includes a second type of interaction with the input mechanism, wherein the second type of interaction is different from the first type of interaction, initiating a process to power off the computer system.

A non-transitory computer readable storage medium storing one or more programs, the one or more programs comprising instructions which, when executed by a computer system with a display and an input mechanism, cause the computer system to:

• display a first user interface on the display that corresponds to a locked state of the computer system;
• while displaying the first user interface, detect, via the input mechanism, a first user input;
• and
• in response to detecting the first user input via the input mechanism:
• in accordance with a determination that the first user input includes a first type of interaction with the input mechanism and that the first user input meets fingerprint authentication criteria, replace display of the first user interface with display of a second user interface that is different from the first user interface, wherein the second user interface is a most recently displayed user interface that was displayed before the computer system entered the locked state;
• and
• in accordance with a determination that the first user input includes a second type of interaction with the input mechanism, wherein the second type of interaction is different from the first type of interaction, initiate a process to power off the computer system.
