FreeOTP is a two-factor authentication application for systems utilizing one-time password protocols. Tokens can be added easily by scanning a QR code. If you need to generate a QR code, try our QR code generator.

FreeOTP implements open standards: HOTP and TOTP. This means that no proprietary server-side component is necessary: use any server-side component that implements these standards. We recommend FreeIPA.
