RADIUS MFA

RADIUS (Remote Authentication Dial-In User Service) providers let Casdoor verify a second factor against your RADIUS server during MFA.

Configure the provider

1. Providers → Add.
2. Set Category to MFA, Type to RADIUS.
3. Fill in:
   • Host — RADIUS server IP or hostname (e.g. 10.10.10.10)
   • Port — RADIUS port (default 1812)
   • Client Secret — Shared secret configured on the RADIUS server
4. Save.

Use in an application

Add the RADIUS provider to your application’s provider list. Users can then choose RADIUS as their MFA method. During setup and sign-in, they enter their RADIUS username and password; Casdoor forwards the check to your RADIUS server.
