Complete Guide to Auth with NodeJS & React: JWT, Role Based Access Control, Two-Factor Authentication, Revoke Token

What you'll learn

How JWT access and refresh tokens work, and how to manage them securely
How to implement login, registration, and logout flows from scratch
Best practices for storing tokens in the browser (cookies vs localStorage)
How to protect backend routes using middleware and RBAC
How to build role-based frontend interfaces (Permission dashboards)
How to implement 2FA with QR codes (compatible with Google Authenticator)
How to use Redis to manage refresh token storage
Frontend authentication flow using React, React Router, and Redux

Requirements

Familiarity with Node.js and Express
Familiarity with React.js
Fundamental knowledge of APIs
(Optional but helpful) Experience with tools like Redux and redis

Description

In today's world, secure authentication is no longer optional — it's essential. Whether you're building a startup product, working on enterprise-level software, or simply looking to strengthen your development skills, knowing how to implement authentication and authorization properly is a must.This course is your complete guide to implementing a modern, secure, and scalable authentication system using Node.js for the backend and React for the frontend. We'll walk through real-world practices for handling user login, registration, protected routes, user roles, and advanced security features like 2-Factor Authentication (2FA).You'll begin by learning the foundations of JWT (JSON Web Tokens), how to generate and verify access and refresh tokens, and how to store them securely. Then, we'll dive deep into Role-Based Access Control (RBAC) — giving different permissions to users based on roles like admin, moderator, or customer. You'll learn how to build APIs that enforce these rules safely and efficiently.To take things further, we'll implement Two-Factor Authentication (2FA) using TOTP (Time-based One-Time Passwords). Users will be able to scan a QR code with an app like Google Authenticator and input time-based codes during login, significantly boosting security.This course doesn't just show you how to implement things — it explains why each step is important and how to avoid common pitfalls in building secure systems. You'll follow best practices in both backend and frontend development, and understand the real-world considerations behind authentication systems: token expiration, token rotation, cookie vs localStorage, refresh token reuse detection, and more.

Who this course is for

Full-stack developers who want to implement secure login systems with JWT, role management, and 2FA
Backend developers looking to master authentication, refresh tokens, and role-based access with Node.js
Frontend developers who want to integrate login, protected routes, and 2FA into React apps
Students or self-learners building portfolio projects with real authentication features
