This question was posed to me and I have no idea. Could someone please help?
Is there a way to intentionally fail the Azure
Multi Factor Authentication (aka PhoneFactor) when it calls.
The options are to either press # to confirm success, or 0 to report
fraud, but there needs to be some other button to "fail" the
authentication so that the calls will cease. If you just ignore the
phone call, it will just keep calling, including leaving messages in
ones voicemail.
It's possible that this is not 100% an Azure problem and instead may
have to do with how we have RADIUS configured. Perhaps if we can define
a "maximum" amount of retries, instead of the current, which appears to
be indefinite, then that may be an acceptable solution.
