Restore Iphone
Hi, I am trying to setup my phone but, my wife is not home and she can't give me the 6 digit code, can u help me with that?
No, we cannot. You need another trusted device. You can wait until your wife returns. If you have another phone, then you can call her. You can always request another verification number.
You need another trusted device or telephone number.
See Two-factor authentication for Apple ID - Apple Support:
A trusted device is an iPhone, iPad, or iPod touch with iOS 9 and later, or a Mac with OS X El Capitan and later that you've already signed in to using two-factor authentication.
