keycloak-bff-auth

Keycloak BFF authentication centralizes OAuth2 (OIDC) operations in the backend. You handle JWT verification and RBAC middleware by setting up a Keycloak environment, configuring realms and clients, and managing frontend tokens for secure user identification and route protection.

The BFF pattern for OIDC centralizes authentication in the backend, removing token handling from the browser. It performs JWT verification to securely identify users and manage roles, ensuring API routes and user operations are protected by RBAC middleware.

Yes, you can test JWT verification locally without a Keycloak instance using the Skill's test mode. This mode supports development and testing by generating and validating self-signed tokens, allowing you to build and test RBAC middleware independently.

Keycloak BFF integration requires setting the JWT_SECRET environment variable to sign and verify tokens. You also need to configure client-side token management settings and ensure your Keycloak realm and client configurations are properly defined.

Yes, the BFF approach integrates role-based access control (RBAC) middleware to secure API routes. By verifying JWTs issued by Keycloak, the backend enforces role-based permissions, ensuring only authorized users can access specific operations and endpoints.

Self-signed tokens in test mode bypass actual Keycloak OIDC flows for local development convenience. This limitation means you cannot fully validate real-world OAuth2 provider configurations, token lifecycles, or external client-side token management behaviors until integration.
