Apple did not immediately respond to a request for comment on the security issue.
Barkah discovered that even when voice dialing is disabled, you can get it to work from emergency call screen, the feature designed to let you call 911 or any other phone number without providing access to other parts of the phone.
There is one big snag though--voice calls won't actually go through.
I don't recognize the number, but that's normal.
What's weird is it's a video call, from someone using Duo, Google's video chat app available today for i OS and Android.
That's a bit different than signing into i Cloud; in that scenario, Apple sends a four-digit code to the mobile phone number on file for your account.
