JWT lifecycle management for stateless APIs involves issuing short-lived access tokens on login and validating them on protected routes, using refresh tokens to maintain secure sessions, ensuring scalable authentication.

OAuth2 social login integration uses Passport strategies like passport-google-oauth20 and passport-github2 to handle authentication flows, enabling single sign-on (SSO) and secure delegation without managing provider credentials directly.

RBAC permission-based access control for microservices enforces security boundaries by mapping user roles to specific permissions, ensuring clear separation of concerns and validating authorization rights on protected API routes.

Yes, Redis integrates with express-rate-limit via rate-limit-redis and connect-redis to provide distributed rate limiting and session storage, preventing brute-force attacks on authentication endpoints across scalable microservice architectures.

Yes, bcrypt securely hashes user passwords before storage, while zod validates and sanitizes incoming authentication payloads, together preventing injection attacks and credential leakage during the OAuth2 or JWT login process.

JWT session management is not recommended when immediate server-side session revocation is required, as stateless tokens remain valid until expiration unless paired with a Redis blacklist.
