MERN Stack Full Course | Complete Full Stack Developer Roadmap🚀 - Complete Authentication System | JWT, Refresh Token, OTP, Logout All Devices

Complete Authentication System | JWT, Refresh Token, OTP, Logout All Devices In this video, you will learn how to build a Production-Ready Authentication System using Node.js, Express, MongoDB, and JWT. Instead of a basic login tutorial, this project focuses on industry-level authentication architecture including Access Tokens, Refresh Tokens, Token Rotation, Session Management, Logout from All Devices, and OTP-Based Authentication. By the end of this video, you will understand how modern backend systems manage secure authentication and session lifecycle in real-world applications.
