JWT authentication requires issuing short-lived access tokens and long-lived refresh tokens to validate API requests without storing sessions. This pattern demonstrates token issuance, validation, and secure session handling using common server-side libraries.

OAuth2 integration for social sign-in involves configuring authorization flows with providers like Google or GitHub to delegate authentication securely. This approach demonstrates OAuth2 flows and OpenID Connect integration to establish user identity across modern applications.

RBAC policy enforcement works by assigning users to specific roles and checking those roles against access permissions before allowing API operations. You can apply RBAC and ABAC policies to protect endpoints across both REST and GraphQL services.

Session management is needed when you require server-side state tracking for immediate revocation, while stateless JWT tokens are better for horizontally scalable APIs. This implementation demonstrates both secure session handling and token-based authentication patterns.

Auditing API authentication systems involves reviewing token validation, OAuth2 flows, and RBAC policies for security vulnerabilities. These patterns are suitable for building, securing, or auditing existing APIs by demonstrating token issuance and security best practices.
