概要
This skill provides a comprehensive toolkit for developers building robust identity management and access control systems. It offers production-ready implementation patterns for stateless JWT authentication with token rotation, stateful session management using Redis, and social login via OAuth2/OpenID Connect. Beyond identity verification, it includes sophisticated authorization models such as Role-Based Access Control (RBAC) and granular permission-based logic, making it an essential resource for securing REST/GraphQL APIs and architecting scalable multi-tenant applications.
