Enable OIDC Discovery + +If your provider supports it, switch to OIDC discovery to simplify configuration and ensure endpoints stay up-to-date. + +#### 2. Configure Logout URL + +Set up proper logout handling to ensure users are logged out from both CTFd and the identity provider. + +#### 3. Review Security Settings + +- Ensure your CTFd instance uses HTTPS +- Verify redirect URIs are correctly configured in your provider +- Review provider security settings (e.g., token expiration, refresh tokens) + +#### 4. Monitor Logs + +After upgrade, monitor logs for: +- Successful logins +- Any authentication errors +- Admin promotions +- Team assignments + +#### 5.
