We’re big fans of the pattern lock feature on Android, but taking it one step further is the picture password option in the new Windows 8. Like the pattern lock you have to touch specific points on the screen in order to unlock the device, but here the points are on a picture of your choosing rather than a uniform grid. The developer TwinBlade has now brought the idea over to Android. It uses an image from your gallery, and you can create your lock combination using points, lines and circles. The trick is to position these near or around objects within the image so they are memorable. Picture Password Lockscreen is available in the Play Store.
