Refresh token

[balajiseo]

A refresh token is a special credential used in authentication systems like OAuth 2.0. While short-lived access tokens grant access to resources, the long-lived refresh token is securely stored and sent to an authorization server to obtain a new access token when the old one expires, avoiding repeated logins.

The concept of refresh tokens is quite interesting and practical, especially for applications that require long-term login sessions like mobile apps. I find this approach convenient for users while still maintaining security—provided the tokens are managed properly.
