Oof. I wonder if admins can disable push notifications and just fall back to TOTP instead? Though it does sound like that would not be convenient if you have to enter a TOTP every time an RDP connection get interrupted.
Sorry but the parent poster is correct. For both my corp account as well as my personal Microsoft account , I’m prompted to enter the validation number after I’ve faceid’d.
If this doesn’t happen when you are authenticated, then it’s a setting with the system you’re logging into.
