FreeOTP is a two-factor authentication application for systems utilizing one-time password protocols with support for ​Android (4.0 or later) and ​iOS (7 or later). 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. We personally recommend ​FreeIPA, which uses TOTP. However, any standards-compliant implementation will work. Currently, FreeOTP provides implementations of ​HOTP and ​TOTP.
