App Profile: My PIN Codes

This app helps you remember your PIN codes and other number-based passwords in a simple and secure way – without ever storing the actual codes.

You choose a secret pattern made of four colored tiles. That pattern is all you need to remember. When you later view the grid of numbers, your personal pattern reveals the correct code.

The PIN itself is never saved – only the full number grid is shown, and only you know how to read it.
Using the same pattern, you can safely remember as many codes as you want – no notes, no worries.
