How to turn two code authorization
iPhone 7, iOS 13
Question marked as
If you have an Apple ID already created then you should have two-factor authentication depending on when you created it. If you do not then log in to your Apple ID and you will be presented with either to set it up OR to input/verify trusted devices and phone numbers. Best experience to do this is on from your computer and the Apple ID website-->>https://appleid.apple.com
Hope this helps.
