How do I turn off two factor identification

Hello,

I see you want to disable two-factor authentication. 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 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.

Two-Factor Authentication is tied to your Apple ID not a specific device.

If you recently turned it on (less than 2 weeks ago), you can use the link in the email you received after turning it on, to turn it off.

If this is an Apple ID or recent creation or it has been more than 14 days since it was turned on, it can no longer be turned off.

It should be transparent in normal use, and you should only encounter it if you are logging in to a new device with your Apple ID, or are trying to access an Apple website such as iCloud.com or https://appleid.apple.com

You don't.

If you are looking to sell or give away your device and worried about the two factor authentication, follow the steps in this support article. Two factor authentication is tied to your Apple ID, not the device. People who had an Apple ID before it was required to have two factor authentication could turn it on and an email was sent that would allow them to shut it back off within 2 weeks only by clicking a link in that email. This is not available when creating an Apple ID now.
