-Confirm: Prompts you for confirmation before running the cmdlet.
-DeviceAuthenticationEnabled: Specifies whether device authentication is enabled for the global policy.
-DeviceAuthenticationMethod: Specifies the device authentication method.
-PassThru: Returns an object representing the item with which you are working. By default, this cmdlet does not generate any output.

Set-AdfsGlobalAuthenticationPolicy -PrimaryExtranetAuthenticationProvider @('FormsAuthentication', 'CertificateAuthentication')

This command sets the primary extranet authentication policy to forms-based or certificate-based authentication. In this case, the user is provided a choice when the user logs on to an application protected by AD FS from the extranet. Source: Microsoft, CC BY 4.0; transcript prompt/output removed.
