Editor's Overview

PINcredible - Secure PIN vault is a password & 2fa application developed by Cyb3rKo, packaged as a single Android APK of version 1.0 weighing in at 3.35 MB. The package targets Android 4.1+ and above. Below you'll find the publisher's own description, a quick spec sheet, and a short buyer-beware checklist so you know exactly what you're installing before tapping download.

Install Checklist

  1. Only download through the button on this page — never from third-party mirrors or shortened links, which are the most common way malware spreads.
  2. File size is a light 3.35 MB, so it installs quickly even on modest connections.
  3. This build is signed by "Cyb3rKo" — always verify the developer name matches what's listed on the app's official store page before installing an update.
  4. After install, Android may prompt you to allow "Install from unknown sources" — approve only this one install, then revoke the permission in Settings > Apps > Special access.
  5. We link directly to the APK file or the publisher's repository; we do not modify the binary. Always run a virus scan after any sideloaded install.

About this app

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
  • 🔢 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.
