auth-implementation-patterns

Implement JWT authentication in Express by generating access and refresh tokens using jsonwebtoken, validating them via middleware, and enforcing role-based access control (RBAC) by checking user roles before routing to sensitive API endpoints.

Secure user passwords by applying bcrypt hashing to credentials before storage. Validate credential payloads with zod schemas and enforce rate-limit-redis to prevent brute-force attacks during the authentication process.

Yes, the authentication approach supports OAuth2 and OpenID Connect flows using passport strategies, alongside session-based authentication managed by express-session for secure access control in web applications.

Set up rate limiting for secure API endpoints by configuring rate-limit-redis to track and restrict incoming client requests, mitigating credential stuffing and brute-force vulnerabilities during the user login process.

Use JWT for stateless, distributed API authentication where tokens carry user identity and roles, whereas session-based authentication via express-session is suited for stateful web applications requiring strict server-side access control.

Enforce resource ownership by validating the authenticated user's ID against the resource owner's ID, and apply permission-based checks within your RBAC implementation to restrict access to sensitive data based on user roles.
