-You can deploy Windows Hello for Business key trust in non-federated and federated environments.  For non-federated environments, key trust deployments work in environments that have deployed [Password Synchronization with Azure AD Connect](https://docs.microsoft.com/azure/active-directory/connect/active-directory-aadconnectsync-implement-password-synchronization) and [Azure Active Directory Pass-through-Authentication](https://docs.microsoft.com/azure/active-directory/connect/active-directory-aadconnect-pass-through-authentication).  For federated environments, you can deploy Windows Hello for Business key trust using Active Directory Federation Services (AD FS) beginning with Windows Server 2012 R2.
