How does two Factor authentication work with one phone if it breaks
I only have one iPhone so I don’t have two factor authentication on What I want to know is if I turn it on will I still be able to get the message if my phone breaks. (like say my phone is broken I get a new phone get and new my Sim card and put it in the new phone so my new phone has the same number how do I can then get the code because your phone is locked until you sign in to Apple and how do I get the backup from iCloud without the two factor authentication sign in)
if you have a YouTube vid demonstration
that would be helpful I’m so confused about this? Plz help
iPhone XS, iOS 14
