 === Enable OIDC authentication
 
-To configure OIDC, choose one of two modes:
-
-* *Runtime acquisition mode:* Redpanda Console obtains a token from the IdP.
-* *Static token mode:* You provide a pre-acquired OIDC token.
+When you enable OIDC authentication, Redpanda Console uses an external IdP to authenticate users. This allows for single sign-on (SSO) and centralized user management.
 
 Redpanda and Redpanda Console require OAuth 2.0-compliant JWT tokens for user authentication. When using OIDC, your IdP must issue JWTs. Redpanda Console uses these tokens to authenticate to Redpanda APIs through SASL/OAUTHBEARER or Bearer headers.
