What is the difference between JWT and refresh tokens?

JWT (JSON Web Token) is a compact, URL-safe means of representing claims to be transferred between two parties. Refresh tokens, on the other hand, are used to obtain new access tokens without requiring the user to log in again.

Why would I use a refresh token instead of just a JWT?

Using a refresh token allows for better security and user experience. It enables you to keep access tokens short-lived, reducing the risk if an access token is compromised.

How do I implement refresh tokens in my application?

To implement refresh tokens, you typically store them securely on the client side and use them to request new access tokens from your server when the current access token expires.

Are there any security concerns with using refresh tokens?

Yes, refresh tokens should be stored securely and transmitted over HTTPS to prevent interception. Additionally, consider implementing token revocation mechanisms.
