Dynamic pin|工具線上App不用買-HotApp4Game

Lock your screen and apps with state-of-the-art authentication algorithm.

Dynamic pin helps to secure your PIN from shoulder surfing and key loggers.

When you type the same PIN every time, there is a good chance your friends , electronic surveillance or others knowing it . How will you avoid that ?

Dynamic Pin changes the pin based on an expression you set in the application. After every use, the pin is destroyed and new pin is generated. Only the user, who know the expression can evaluate the new pin. Deducing the expressions from pin is not a trivial task .

You can set any expression like a+d , a*f , g-c ...

Notification details about matrix will appear on every restart.

Apps unlocked remain unlocked till screen goes off.

SCREEN LOCK IS FOR NON-ENCRYPTED DEVICES ONLY.

***If your expression encounters divide by zero , the result is zero .

In HTC and Sony devices, matrix will be shown when Emergency Call is clicked on the lock screen.

By default numbers used in the matrix are binary , only 0s and 1s . So pin varies among 0000 , 0001 and 0002 . You can change this option to use single digit numbers ( 0 - 9 ) .

Prefer manual update for this app because play store does not restart killed service after an update.
