SMS-OTP Mechanism
A short message service one time password (SMS-OTP) is a free RADIUS module to implement two factor authentication. There are
multiple 2FA mechanisms that can be deployed with the RADIUS. Mechanisms such as the Google authenticator do not rely on the
Access-Challenge message and the SMS-OTP module rely on the Access-challenge message. The main objective of this feature is to
handle the Access-Challenge messages and sends the Access-Request message with user’s response.
This module requires NAS for handling the access challenge from the RADIUS server. NAS sends the input OTP in an Access-Request to
the RADIUS server, and the user authentication succeeds or fails depending upon the Access-Accept or Access-Reject response received
at NAS from the RADIUS server.
