Access and Refresh Token in Backend || Token Authentication in React & Node
In this video, we dive deep into Access and Refresh Tokens using React.js and Node.js (Express) to build a secure authentication system using JWT
💡 You'll learn:
Why access tokens alone aren't safe
How refresh tokens work
What to do when access or refresh tokens expire
Frontend and backend code walkthrough
Full implementation demo using React and Node.js
This is an essential concept for anyone building full-stack applications (especially MERN stack). Also, it's a frequently asked topic in interviews!
