No one from Microsoft is responding to this issue for WVD PASSWORDLESS LOGIN

Have a question about passwordless too, more like is it supported and in which scenario.

Found some info in here:

Passwordless authentication with Microsoft Authenticator phone sign-in

https://www.jasonsamuel.com/2019/03/04/how-to-setup-password-less-phone-sign-in-authentication-with-microsoft-authenticator-azure-ad-and-citrix-workspace/ which I have talked about many times in the past is supported by Azure AD, therefore it is supported by WVD. Authentication happens before authorization and enumeration of the WVD service. Since WVD is a native Azure service, it is able to support Azure AD natively as a result. There is nothing you need to do to make this work. It’s already built-in, you just need to enable it under Azure AD in Authentication Methods for your users as I have previously discussed https://www.jasonsamuel.com/2019/09/18/how-to-enable-fido2-password-less-authentication-with-microsoft-azure-ad-for-use-with-windows-10-and-saas-web-apps/#Enabling_Authentication_Methods_and_FIDO2_Security_Keys_for_your_Azure_AD_tenant.
