Udemy – NodeJS & React Authentication: JWT, Role-Based Access, 2FA 2025-3

NodeJS & React Authentication Course: JWT Role-Based Access 2FA. This course will cover the complete implementation of a secure and efficient authentication system using Node.js and React. In this course, participants will be introduced to the basic and advanced concepts of authentication and authorization and will learn how to implement them in practice. The course begins by explaining the basics of JWT (JSON Web Tokens) and teaches how to generate, verify, and securely store access and refresh tokens. It then covers the topic of Role-Based Access Control (RBAC) and explains how to assign different access levels to users based on roles such as administrator, supervisor, or customer. Participants will learn how to create APIs that enforce these rules securely and efficiently.

The course will continue with the implementation of two-factor authentication (2FA) using TOTP (Time-based One-Time Passwords). Users will be able to scan a QR code using apps like Google Authenticator and enter time-based codes when logging in, which significantly increases security. This course not only teaches you how to implement it, but also explains why each step is important and how to avoid common mistakes in building secure systems. Participants will learn best practices in backend and frontend development and understand real-world considerations for authentication systems, including token expiration, token rotation, using cookies versus localStorage, detecting refresh token reuse, and more.

What you will learn

How JWT access and refresh tokens work and how to manage them securely.
How to implement user 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 front-end user interfaces (permission dashboards).
How to implement 2FA with QR codes (compatible with Google Authenticator).
How to use Redis to manage refresh token storage.
Front-end authentication flow using React, React Router, and Redux.

This course is suitable for people who:

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.
Front-end developers who want to integrate login, protected routes, and 2FA into React applications.
Students or self-taught individuals who build portfolio projects with real-world authentication features.
