Is it compatible with Pydantic v2?

The provided configuration patterns use pydantic-settings, making it fully compatible with modern Pydantic v2 FastAPI applications.

Does it support token refreshing?

Yes, it provides an authentication service for exchanging refresh tokens for new access tokens and includes middleware to monitor token expiration.

How does this skill handle JWT validation?

It uses the python-jose library to decode tokens and validates them against Keycloak's JWKS endpoint for secure RS256 signature verification.

Can I use this for Role-Based Access Control (RBAC)?

Yes, it includes specific FastAPI dependencies to verify both realm-level and client-level roles before allowing access to specific API routes.

API Development

Integrates Keycloak identity management and OIDC authentication into FastAPI backends with robust role-based access control.

This skill provides production-ready patterns for connecting FastAPI applications with Keycloak as an identity provider. It automates the setup of OIDC/OAuth2 configurations, implements secure JWT token validation using JWKS, and provides pre-built FastAPI dependencies for user extraction and granular role-based access control (RBAC). It is an essential tool for developers building secure enterprise APIs that require Single Sign-On (SSO), automated token refresh logic, and sophisticated multi-tenant authentication patterns.
