  • replace google authenticator with open source app
  • store totp tokens encrypted
  • backup two-factor accounts with openpgp
  • scan qr codes for otp setup
  • use hotp and totp on android

When to choose

  • you want a free, open-source, minimal-permission authenticator on Android
  • you need OpenPGP-encrypted or password-protected backups of your tokens
  • you want dark/black OLED themes and Google Authenticator compatibility

When to avoid

  • you need actively maintained software with security updates - the project is officially unmaintained
