Hi, To give the background, The task is to build bio authentication app/service on windows 10, which prompts the authentication every "x" amount of time interval. Is there such a default configuration for Windows Hello out-of-the-box , to re-authenticate at an interval ? If yes, how does it work, where can I find detailed information about it ? How to set it up? Is there such a thing as Windows Hello C# API? To look for more documentation about how to access locally stored data and validate user input against Windows Hello fingerprint for example? Is it possible for the service to block everything else while re-authenticating, something like a lock screen ? Kind regards!

Hi,

The task is to build bio authentication app/service on windows 10, which prompts the authentication every "x" amount of time interval.

Is there such a default configuration for Windows Hello out-of-the-box , to re-authenticate at an interval ? If yes, how does it work, where can I find detailed information about it ? How to set it up?

Based on this document, it mentions after the device has recognized the user, it still must authenticate the user before determining whether to grant access to a requested resource or you can force the user to log in again. If you want to validate user input against Windows Hello fingerprint, you could try to use UserConsentVerifier Class to perform a verification. In addition, here is an official sample, you can check it.
