Doesn’t work if you use a hardware key 🔑 for auth
Nor if you don't click "allow" on the pop up, as far as I know. Someone showed me a medium article that revealed some details, among which was fact that the Atlanta Apple Store got hacked or leaked or some such thing. Perps were able to create real help tickets and such too, and quite skilled on phone.
