Overview

The open source solution for two-factor authentication, accommodating many different OTP algorithms using a modular approach. This includes the OATH standards such as HMAC (RFC 4226) and time-based HMAC. But LinOTP's design makes it easy to create your own tokens with different algorithms, including challenge-response tokens, tokens based on QR codes, and tokens based on push-type messages.
