# Customize the reverification window

You can now customize how long a successful sign-in or reverification remains valid for Clerk-protected sensitive actions. Set the reverification window between 1 and 10 minutes. The default remains 10 minutes.

A shorter window can prompt users to verify their credentials more often before actions such as changing a password, adding and removing an email address, revoking a session, or deleting an account.

To configure the window, open the [**Sessions**](https://dashboard.clerk.com/~/sessions) page in the Clerk Dashboard. Under **Session lifetime**, set **Reverification window** to the number of minutes you want, between 1 and 10.

This setting applies to [sensitive actions protected by Clerk](https://clerk.com/docs/guides/secure/reverification.md#sensitive-actions-that-require-reverification). For sensitive actions unique to your application, define the required window in your application. See the [reverification guide](https://clerk.com/docs/guides/secure/reverification.md) for details.
