Take off two factor authentication for

Hello ~This is from the article you came from…

*If you're already using two-factor authentication with your Apple ID, you can't turn it off. If you updated to two-factor authentication inadvertently, you can turn it off within two weeks of enrollment. If you do, your account is less secure and you can't use features that require a higher level of security.

Two factor authentication is tied to your Apple ID, not a specific device.

It can not be disabled once it is in use.

Hello ~ You are most welcome.
