Access tokens and refresh tokens play key roles in providing a seamless user experience by allowing users to access applications without repeated logins.
Access tokens are stored in the user's browser as cookies and are short-lived, typically lasting around 1 hour, enhancing application security by expiring quickly.
Refresh tokens, on the other hand, are stored in the application's database and as browser cookies, having a longer lifespan, usually in terms of days.
When an access token expires, the refresh token is used to request a new access token without requiring the user to log in again, ensuring continuity of the user/client session.
