Azure mfa NPS extension RDS Gatway method

Question

Hi there,
I´ve setup RDS Gateway onprem with Azure MFA NPS extension, but it seems it only works with Auth. App as method ? so no txt or call ? is that true?
Thank you

Answer 1

The available methods depend on:

• The methods available through the interface of the RADIUS client (the appliance/device/server being signed in to). If this interface does not offer to insert a text value, then you can't use the SMS-based one-time password or the hardware token-based one-time password verification method.
• The verification options available in the legacy PhoneFactor portal experience. When a method is disabled there, than it won't be available for any multi-factor authentication prompt, including through NPS.
• Security Defaults. When this Azure AD feature is enabled, than the Authenticator App notification is the only method available for multi-factor authentication.

Answer 2

@geniadk RDP interface don't have an option to type in the OTP that you receive via SMS. So, in case of RDP, you can use only those methods which don't require user input for second factor authentication.

Supported methods are: Phone call, Authenticator app with notification.
Unsupported methods are: SMS, Authenticator app with PIN.
