How are refresh tokens protected from theft?

Refresh tokens are stored in httpOnly, Secure, and SameSite cookies to prevent client-side JS access (XSS) and are hashed in the database.

Does this skill handle password hashing?

Yes, it uses bcrypt with a recommended work factor of 12 for secure password storage and verification.

What happens if a refresh token is stolen and reused?

The skill implements rotation and reuse detection; if an old token is used, the system can revoke all active sessions for that user as a precaution.

Does it include frontend integration code?

Yes, it provides a pre-configured Axios instance with request and response interceptors to handle the 'silent refresh' flow automatically.

API 开发

Implements a production-grade JWT authentication flow with refresh token rotation and secure cookie management for MERN applications.

This skill provides a comprehensive blueprint for implementing robust JWT-based authentication in MERN stack projects. It automates the creation of secure registration and login endpoints, handles short-lived access tokens alongside long-lived refresh tokens, and ensures high security through httpOnly cookies and server-side token rotation. Ideal for developers building secure full-stack applications, it includes both backend logic for Node/Express and frontend interceptors for React/Axios to handle silent refreshes and session management seamlessly while protecting against common vulnerabilities like XSS and CSRF.
