Abstract: A non-transitory machine-readable storage medium, having encoded thereon program code is provided. When the program code is executed by a machine, the machine implements a method for operating an application on an electronic device without having to perform numerous steps to access the predetermined feature after unlocking the device for functions that require authentication. The method includes the steps of providing an electronic device requiring a password to unlock the device, the device having a screen, wherein the device is locked; receiving a first recognizable scribbled pattern on the screen, the pattern being provided by a user, wherein the first recognizable scribbled pattern is associated with a first specific application; and unlocking only the specific application for use by the user.
