Extend Windows Hello with a new authentication method

Question

Is there a way to add a new custom authentication method on Windows Hello based on my code? I saw there is GINA but it's not an API and it's difficult to use with languages different from C++.

Answer 1

Windows Hello assumes Windows 10. In this case you must implement a Credential Provider.

Have a look at Microsoft Credential Provider API Interfaces and Docs

In this case there are exist solutions to implement the provider using C#.
