How to turn off two-factor authentication
Anyone know how to turnoff Two-Factor Authentication on a MacBook Pro, iPad, and iPhone? Thanks.
MacBook Pro
If Two-factor authentication is active it cannot be turned off.
See Two-factor authentication for Apple ID:
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, you can unenroll within two weeks of enrollment.
