概要
This skill provides comprehensive guidance and implementation patterns for building secure, scalable access control systems. It covers the full spectrum of modern security needs, from basic session-based authentication to stateless JWT architectures and OAuth2 social login integrations. Developers can use this skill to quickly scaffold robust role-based access control (RBAC), manage secure token lifecycles with refresh flows, and ensure their APIs follow industry security best practices. Whether you are migrating legacy auth systems or building a new multi-tenant application, it offers production-ready patterns for Express, TypeScript, and Redis.
