andOTP - Android OTP Authenticator

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.

Features:

• Free and Open-Source
• Requires minimal permissions
  • Camera access for QR code scanning
  • Storage access for import and export of the database
• Encrypted storage
• Sleek minimalistic Material Design
• Great Usability
• Compatible with Google Authenticator

TODO

• Export the secret key (maybe)
