JWT authentication secures API backends by issuing access and refresh tokens. This pattern manages token rotation and validation, providing robust stateless session handling for modern web applications.

Role-Based Access Control (RBAC) in multi-tenant systems restricts data access via permission checks. This pattern enforces authorization rules across microservices, ensuring users only access permitted tenant resources.

OAuth2 integration enables social logins and SSO by delegating authentication to external providers. This pattern manages token exchange flows, allowing applications to verify identities without handling raw credentials.

Session-based authentication with secure cookies is preferred when you need server-side state control. Unlike stateless JWTs, this pattern allows immediate session revocation and detailed auditing for sensitive applications.

Password handling and rate limiting require hashing credentials and throttling requests to prevent brute-force attacks. These security best practices protect endpoints and maintain system integrity during access control validation.

Yes, the jsonwebtoken dependency is required for JWT-based authentication patterns. It provides the core cryptographic functions to sign, verify, and decode tokens for secure API session management.
