Configure kiosk reset after idle timeout
You can configure Microsoft Edge to reset to the configured start experience after a specified amount of idle time. The reset timer begins after the last user interaction. Resetting to the configured start experience deletes the current user’s browsing data. If enabled, you can set the idle time in minutes (0-1440). You must set the Configure kiosk mode policy to 1 and configure Microsoft Edge in assigned access as a single app for this policy to work. Once the idle time meets the time specified, a confirmation message prompts the user to continue, and if no user action, Microsoft Edge resets after 30 seconds. If you set this policy to 0, Microsoft Edge does not use an idle timer. If disabled or not configured, the default value is 5 minutes. If you do not configure Microsoft Edge in assigned access, then this policy does not take effect.
