[!INCLUDE hello-on-premises-key-trust]

Key trust deployments need an adequate number of 2016 or later domain controllers to ensure successful user authentication with Windows Hello for Business. To learn more about domain controller planning for key trust deployments, read the Windows Hello for Business planning guide, the Planning an adequate number of Windows Server 2016 or later Domain Controllers for Windows Hello for Business deployments section.

Note

There was an issue with key trust authentication on Windows Server 2019. If you are planning to use Windows Server 2019 domain controllers refer to KB4487044 to fix this issue.

The key registration process for the On-premises deployment of Windows Hello for Business needs the Windows Server 2016 Active Directory or later schema.

The minimum required domain functional and forest functional levels for Windows Hello for Business deployment is Windows Server 2008 R2.
