Hello, Recently I created a new Apple ID, through my mac preferences (macOS Sierra 10.12.5). When creating the account, I was prompted to fill my phone number to receive a verification code. This is the so called Two-Factor Authentication. After I finished the process, I went on to create an iCloud mail address (***@icloud.com). Having an icloud email address was the main reason I created the new Apple ID. When everything was set I signed in to appleid.apple.com, to check my settings: Apple had my phone number stored as a verified phone number. However I do not wish to have my phone number connected to my Apple ID (for personal reasons). I went to check wether I could turn the Two-Factor Authentication off, but apparently I cannot do that, since I created my Apple ID on a device running the latest (as of June 2017) version of macOS (see bottom of this page). So my idea was: If I delete me iCloud email account (i.e. the ***@icloud.com address) and create a new Apple ID from a device that is running an older software, will I be able to use the same ***icloud.com address with my new Apple ID? And If so, could you please help me do that... And if my idea is not possible, can I at least remove my phone number, or the two-factor authentication from my current Apple ID? Thanks in advance.
