About Picture Password
Picture Password is a new method of securing your device that allows you to use a combination of a number (0 to 9) and picture to unlock your device instead of typing a password. When enabled, instead of unlocking your device using a password, you’ll be shown a picture and a grid of random numbers. To unlock your device, tap anywhere on the screen and drag the number grid until your number is on top of a specific spot.
Picture Password not only provides you with a quick and easy way to unlock your device, it also helps prevent other types of attacks such as:
+ Smudge Attack – Picture Password always shows a random number grid whenever you unlock your device, which means you never follow the same pattern. In other words, because you always move your number from a different location on the grid, an attacker cannot establish a smudge pattern.
+ Shoulder Surf Attack – When using a simple password, someone could look over your shoulder while you enter it. Picture Password prevents this situation from occurring by drawing a random number grid and varying the size of the grid. For example, in addition to a random number grid, the grid size also randomly changes increasing and decreasing the amount of rows and columns to reduce the shoulder attack vulnerability.
+ Brute Force Attack – Picture Password addresses brute force attacks by limiting the number of guesses, varying the size, location, and pattern of the grid numbers and requiring minimum movement of the number grid.

Nice app. Missing 1star for maximum try, add infinite please and add option to turn off wrong notofication. And also add animation when open screen, not only swiping down. Its great app

Should be standard in Android. The pop ups when the number is wrong is also annoying. The grid should just refresh with new random numbers. Also, I don't want a lock screen before deactivating an alarm.

I have the system password running too for better security (locks after 1 hour). Every time the system password locks the phone this shows a black screen and I have to hit the home button to unlock the phone. Hope you can fix that.

Picture Password is killed by optimizing applications, So, Add a service to Picture Password which will restart it when killed by optimizing applications...

Stop puting the unlock number so close to the unlock point and also put only 1 or 2 of the number on the screen as well as away from the unlock point

I've been looking for an android version of the truly excellent Picture Password feature on the BB10 OS. This is the closest replica of that but needs a little fine tuning to be considered the same. Improvements needed: 1. The positioning of the selected digit for unlocking is often either exactly over the chosen point of the picture or not visible at all. 2. Occasionally the lock screen does not show when waking up the phone, rendering it insecure. 3. False failure of unlock position when unlocking.
