Picture Password Lockscreen allows you to unlock your phone by drawing gestures such as points, lines, and circles on your chosen images. It frees users from the traditional and less secure unlock methods because there are close to an infinite number of combination of gestures. It provides an effective layer of protection against the two most common methods of illegal access gaining to a device- brute-force password hacking and shoulder-surfing.

Forget PIN codes or patterns, you can now draw points, lines, and/or circles to unlock your phone.

To setup, select the background image and draw the gestures. To unlock, draw the saved gestures on the lockscreen.
