# FreeOTP (open-source security app)

> FreeOTP is a free, open-source security app for Android. Two-factor authentication. It has 1,676 GitHub stars and is released under the Apache-2.0 license, and you can install it from F-Droid and Google Play.

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).
