How to turn off two factor authentication

Hello,

If you are getting a new telephone number then edit your telephone numbers. To edit your list of trusted items refer to the section: About trusted phone numbers and trusted devices in the document Two-factor authentication for Apple ID - Apple Support

To see, add, or change your trusted phone numbers:

- On your iPhone, iPad, or iPod touch: Go to Settings > your name > Password & Security. Next to Trusted Phone Number, tap Edit.

- On a Mac: Choose Apple menu  > System Settings (or System Preferences), then click your name (or Apple ID). Click Password & Security, then add or remove a trusted phone number.

- In a web browser: Go to the Account Security section of https://appleid.apple.com/

I see you say you want to disable two-factor authentication, but if you simply edit your numbers this will not be necessary, even if possible. For some background I suggest you read the document: "Two-factor authentication for Apple ID" - Two-factor authentication for Apple ID - Apple Support

Several years ago Apple transitioned to using two-factor authentication for additional account security. Accounts created since that time automatically use two-factor authentication and this cannot be disabled.

Some people have older accounts from before two-factor authentication was mandatory on new accounts. Apple encourages those users to transition to two-factor authentication when signing in on their accounts because without it "your account is less secure and you can't use features that require a higher level of security." Those owners of older accounts who have just activated two-factor authentication have two weeks to change their minds and return to older security settings.

If you have an older account, recently activated two factor authentication, and you're within the two week period for turning it off again, you should check for an email from Apple for a way to do this. If you don't see one about this, look in your junk mail folder.
