1. A method, comprising:
performing a first user authentication for unlocking a touch screen of an electronic device;
recording a first time when the first user authentication succeeds;
detecting a first input for executing an application program when the touch screen is unlocked, wherein the application program is configured to require a second user authentication for executing the application program, and wherein the first input is detected at a second time after the first time;
comparing a time interval between the first time and the second time with a preset time threshold to detect whether the time interval is less than the preset time threshold or the time interval is greater than the preset time threshold;
starting the application program without performing the second user authentication when the time interval is less than the preset time threshold and the first user authentication succeeds; and
locking the application program and requiring the second user authentication to start the application program when the time interval is greater than the preset time threshold.
