2 Factor Authentication 

From the article below. 

Can I turn off two-factor authentication after I’ve turned it on?

If you already use two-factor authentication, you can no longer turn it off. Certain features in the latest versions of iOS and macOS require this extra level of security, which is designed to protect your information. If you recently updated your account, however, you can unenroll for a period of two weeks. Just open your enrollment confirmation email and click the link to return to your previous security settings. Keep in mind, this makes your account less secure and means that you can't use features that require a higher level of security.

To setup your new phone, you can still generate a usable code on your old phone.

If you don’t have your old phone or another trusted device, send the code to one of your pre-configured trusted numbers.
