icon About
Over time I've used several apps to store my PINs, unfortunately none of them really convinced me.
So here we are now, this is my own implementation of a secure PIN manager.

Features


The app obfuscates the PIN in a table layout surrounded by secure random numbers.
This brings two security benefits:
1. ❔ The app can not know where in the pattern the user given PIN is located at. Attackers can not extract the plaintext PIN.
2. 🕵️ This offers protection against Shoulder Surfing, for example while accessing your PIN in a super market or a bank.

Security Aspects
For technical details about the implemented security take a look at the GitHub repo readme.

While you can download the APKs here directly, you should preferably use an F-Droid client so the app stays up-to-date on your device.
