Time-based One-time Passwords (TOTP) from QR codes for two-factor authentication
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 net.bierbaumer.otp_authenticator app written by
Bruno Bierbaumer, which has sadly been inactive since 2015. All credit for the
original version goes to Bruno.
