FreeOTP

Overview

FreeOTP is a two-factor authentication application for systems using one-time password protocols. Tokens are added by scanning a QR code, and the site links to its own QR code generator. It implements the HOTP and TOTP standards, so no proprietary server-side component is needed; the project recommends FreeIPA and is published by Red Hat.

Best for
