I'm trying to configure the security key sign-in option on a group of Hybrid Azure AD joined Windows 10 devices. I've configured a targeted Intune deployment by following the steps on this page: https://docs.microsoft.com/en-us/azure/active-directory/authentication/howto-authentication-passwordless-security-key-windows
My Windows 10 version 1903 devices show up in Azure AD as Hybrid Azure AD joined.
I've enabled the FIDO2 Security Key Authentication Method Policy (Preview).
I've registered my security key as an Azure MFA method in myprofile.microsoft.com.
I've created a Device Configuration Profile in Intune that sets the ./Device/Vendor/MSFT/PassportForWork/SecurityKey/UseSecurityKeyForSignin setting to 1.
I've assigned this Device Configuration profile to my Hybrid Azure AD devices.
At this point, I am able to login to my Azure AD user account with the security key via a browser.
I should be able to login to my Hybrid Azure AD devices using my security key. But, on the Windows 10 logon screen, the 'Sign-In Options" is not even available.
Any help is appreciated.
Thanks
