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.
