andOTP

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 Authenticator app written by Bruno Bierbaumer, which has sadly been inactive since 2015. All credit for the original version goes to Bruno.

  • Free and Open-Source
  • Encrypted storage
  • Plain-text backups
  • Encrypted backups using OpenPGP
  • Sleek minimalistic Material Design
  • Great Usability
  • Compatible with Google Authenticator

Requires minimal permissions:

  • Camera access for QR code scanning
  • Storage access for import and export of the database
