The official open-source Android app for 2FAS, a two-factor authentication service that generates one-time passwords (TOTP and HOTP) for securing online accounts. It works with any service supporting the TOTP/HOTP standard, such as Google, Microsoft, and Dropbox.
Use cases
- generate TOTP codes for two-factor authentication on Android
- open source authenticator app alternative to Google Authenticator
- store 2FA tokens for multiple online accounts
- secure accounts with one-time passwords
- migrate authenticator tokens to a privacy-friendly app
When to choose
- you want a free, open-source TOTP/HOTP authenticator on Android
- you need compatibility with any standard 2FA-enabled service
- you prefer an actively maintained app with public source code
When to avoid
- you need an iOS authenticator (this is Android-only)
- you require push-based or FIDO2/WebAuthn authentication rather than OTP codes
- you need a cross-platform desktop authenticator
