PINcredible - Secure PIN vault
Modern and secure Android app to help you remember any PIN
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.
