Refresh Tokens

Part of the Full Stack Developer Roadmap.

Summary

A longer-lived token used to silently obtain a new short-lived access token, keeping users logged in on the frontend without forcing frequent re-authentication.

How to Learn This

1Implement a refresh-token endpoint and call it automatically from the frontend when a request returns 401.
2Learn why access tokens are kept short-lived and refresh tokens longer-lived.
3Decide where to store the refresh token on the frontend, weighing XSS and CSRF risk.
