This skill provides comprehensive guidance for building robust authentication and authorization architectures in modern web applications. It offers standardized implementation patterns for stateless JWT flows, stateful session management with Redis, third-party social logins via OAuth2/OpenID Connect, and granular access control models like RBAC and PBAC. It is an essential resource for developers securing REST or GraphQL APIs, migrating legacy auth systems, or debugging complex security middleware to ensure industry-standard security compliance.
