andOTP

Open source two-factor authentication for Android. It implements Time-based One-time Passwords (TOTP) and HMAC-Based One-Time Passwords (HOTP). Simply scan the QR code and login with the generated 6-digit code. This project started out as a fork of the great OTP Authenticator app written by Bruno Bierbaumer, which has sadly been inactive since 2015. By now almost every aspect of the app has been changed/re-written so the fork status of the Github repository got detached upon user request. But all credit for the original version and for starting this project still goes to Bruno.
