What is RADIUS?

Remote Authentication Dial-In User Service (RADIUS) is a networking protocol that provides centralized authentication, authorization, and accounting management for users who connect and use a network service. The RADIUS protocol is supported by authentication methods in the Smart ID Digital Access component. See also Examples - Set up Nexus OTP and Nexus Mobile Text as 2FA.

RADIUS client and RADIUS server

A RADIUS client is the client connecting to a RADIUS server for authentication.

  • The RADIUS client can be the policy service, a firewall, or the RADIUS plug-in for the policy service.
  • Usually, the RADIUS server is the authentication service, but it can proxy the access request to another authentication server, depending on the authentication method being used.

RADIUS back-end server

RADIUS back-end servers refer to authentication servers handling third-party authentication methods. The authentication service can proxy access requests to one or several back-end servers. A back-end server can be an RSA SecurID Server, for example.
