PINcredible app

PINcredible is Security tool that is open source under the Apache-2.0 license. 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.

  • 🔢 PIN obfuscation
  • 🔐 Local Encryption
  • 🎨 Modern Design
  • 🌐 No Internet Connection required
  • 🎞️ No Ads
  • 🗿 No Suspicious Permissions

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.
