Time-based One-time Passwords (TOTP) from QR codes for two-factor authentication
Added: 19-07-2017

andOTP is a two-factor authentication App for Android 4.4+.

It implements Time-based One-time Passwords (TOTP) like specified in RFC 6238. Simply scan the QR code and login with the generated 6-digit code.

This is a fork of the great OTP Authenticator app written by Bruno Bierbaumer, which has sadly been inactive since 2015. All credit for the original version goes to Bruno.
