Node.js Authentication with JWT: Secure Implementation Guide
Implement secure JWT authentication in Node.js with refresh token rotation, httpOnly cookies, and RBAC. This guide covers common security pitfalls and production patterns.
Authentication is critical for any application. Here is the secure way to implement JWT in Node.js.
Access Tokens and Refresh Tokens
Use short-lived access tokens (15 min) with long-lived refresh tokens (7 days). Implement rotation on each refresh.
httpOnly Cookies
Store tokens in httpOnly, Secure, SameSite cookies — never in localStorage.
Role-Based Access Control
Implement RBAC middleware that checks user roles before processing requests.
Password Hashing
Use bcrypt with a cost factor of 12+ for password hashing.
Rate Limiting
Limit login attempts to prevent brute force attacks.
