Actually this could be either iPhone or Mac:
I'm investigating switching to 2FA for my iPhones and Macs.
My first question is the need for SMS. I can easily set up the 2FA with SMS in the US, but what happens if I am traveling and have wifi only, due to not using the phone service overseas, or being in a poor cell area at home.
After setup are codes sent via SMS or wifi?
Will 2FA work for me with these possible conditions?
Second question is what happens if I need to login for some reason and a second iPhone/Mac is not with me at the moment? I assume I have to wait until a second computer/phone is available to reset my login?
