Hi Dah•veed,
Yes, the two-factor authentication has enabled(by hacker),
and the mobile number has been lost control!!!!
As this is like a hacker behavior.
I am the apple id owner but the hacker control my appid (not yet have two-factor authentication) & turn on two-factor authentication & setup a new mobile number (not setup any phone number berfor).
the hacker can control this mobile number, and also delete my all trust devices & turn off my security questions.
Currently only the apple id account (email) can prove this apple id is my but not the mobile number!!!
But two-factor authentication only recognized the mobile number or trust devices (but has deleted).
I have try on my iphone device & apple website, all of them need the mobile before go ahead.
Can you tell me how long the waiting period is & how to turn on recover mode!!!
Thanks.
Hary
