Dynamic pin app helps you to secure your PIN from shoulder surfing .

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

Dynamic Pin changes the pin based on the expression you set in the application. After every use, your Pin is destroyed and only the user who knew the expression can evaluate the new Pin from the clue , the matrix . Deducing the expressions from pin is not a trivial task .

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

Basic Pack :

Unlimited application locks.

This pack enables operations among the matrix elements using + , - , * , / , % , ^ .

Examples :

(a*d)+5 - Multiply corner elements of the first row and add 5;

(a+d+m+p) - Add corner elements of the matrix.

Advanced Pack :

This pack enables MIN (a,b), MAX (m,p) functions along with basic pack.
More functions are planned for future releases.

Examples :

MIN(a,d ) - Minimum value between a and d .

MAX(a,b ) - Maximum value between a and b .


1. What is the validation code?
Validation code is a number available on secured lock screen as a toast message. In certain devices message is showed only when emergency dialler is clicked.

2. What is the PIN set before entering one time validation code ?

Note - In devices from HTC and Sony matrix will be shown when Emergency Call window is opened on the lock screen.

Example :

Expression set in the application : a+b
Matrix on lock screen :
a1 b3 c4 d7
e2 f8 g2 h9
i5 j4 k1 l0
m1 n4 o6 p2

Now pin is a+b = 1+3 = 0004

Matrix on lock screen :
a2 b5 c1 d9
e7 f1 g2 h8
i2 j0 k5 l2
m8 n1 o7 p3

Now pin is a+b = 2+5 = 0007

Dynamic pin abstracts the authentication. It offers app lock and screen lock with dynamic pin.

It is a free app with in app purchases.
