FreeOTP

Two-factor authentication
NOTE: Users reported issues with the backup & restore functionality, please test this whenever you install the app on a new device.

FreeOTP is a two-factor authentication (2FA) application for systems utilizing
one-time password protocols (OTP). Tokens can be added easily by scanning a
QR-code or by manually entering in the token configuration.

FreeOTP implements open standards. This means that no proprietary server-side
component is necessary: use any server-side component that implements these
standards - for example FreeIPA, which uses TOTP. Any
standards-compliant implementation will work. Currently, FreeOTP provides
implementations of HOTP (RFC 4226) and TOTP (RFC 6238).

Although APK downloads are available below to give you the choice, you should be aware that by installing that way you will not receive update notifications and it's a less secure way to download. We recommend that you install the F-Droid client and use that.
