Refresh tokens are crucial in scenarios where frequent re-authentication hinders the user experience. One prominent example is in mobile applications, where requiring users to re-authenticate frequently can lead to inconvenience and frustration, as it often involves navigating away from the app.

This issue is particularly pronounced in mobile apps because users expect seamless navigation and minimal disruptions. Re-authentication in these contexts often involves exiting the app to enter credentials, which can disrupt the user's flow and negatively impact their overall satisfaction.

In contrast, for applications accessed through a web browser, refresh tokens do not offer the same level of advantage. This is because web browsers typically maintain user sessions and can manage authentication without the need for constant re-verification.

Therefore, the use of refresh tokens in web-based applications is generally unnecessary and may even introduce unnecessary complexity and potential security risks. The built-in session management capabilities of modern web browsers are sufficient to handle user authentication effectively.
