To implement JWT refresh tokens in a MERN application, you need to set up a refresh token endpoint on your server.
What steps are involved in creating the refresh token endpoint?
First, generate a refresh token when the user logs in, store it securely, and create an endpoint to validate and issue new access tokens.
How do I store the refresh tokens securely?
You can store refresh tokens in an HttpOnly cookie to prevent XSS attacks, or in a secure database.
What should I do if a refresh token is compromised?
If a refresh token is compromised, revoke it immediately and issue a new one to the user after re-authentication.
