This skill provides production-grade implementation patterns for securing Node.js applications with modern authentication methods. It features comprehensive guidance on JWT token handling with refresh token rotation, Google OAuth 2.0 integration, and secure password management using bcrypt and Zod validation. Designed primarily for Fastify-based environments but adaptable to other frameworks, it ensures that your backend services follow security best practices like short-lived access tokens, secure cookie handling, and role-based access control (RBAC) to protect sensitive user data.
