Devices are in Workgroup. How do you plan to use Authenticator without joining the devices to the domain?

From: https://docs.microsoft.com/en-us/azure/active-directory/authentication/howto-authentication-passwordless-phone Prerequisites To use passwordless phone sign-in with the Microsoft Authenticator app, the following prerequisites must be met: Recommended: Azure AD Multi-Factor Authentication, with push notifications allowed as a verification method. Push notifications to your smartphone or tablet help the Authenticator app to prevent unauthorized access to accounts and stop fraudulent transactions. The Authenticator app automatically generates codes when set up to do push notifications so a user has a backup sign-in method even if their device doesn't have connectivity. Latest version of Microsoft Authenticator installed on devices running iOS 8.0 or greater, or Android 6.0 or greater. The device on which the Microsoft Authenticator app is installed must be registered within the Azure AD tenant to an individual user.

Don't take out of context what you're copying here. "The device that runs Microsoft Authenticator must be registered to an individual user." They are talking about Android devices that run the Microsoft Authenticator, not the Windows 10 computer that you want to not use Passwords. https://learn.microsoft.com/en-us/azure/active-directory/authentication/howto-authentication-passwordless-phone

So due to the user being in workgroup they first have to join AAD correct?

No. If you wanted the workstation creds to be the same as contoso.com then yes but it doesn't ask you to configure that.
