I want to Remove two-authentication Code

Hello dunya240,

This page can help out with providing information regarding turning off two-factor authentication for the Apple ID: Two-factor authentication for Apple ID - Apple Support

On there it'll help to note the following:

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.

Cheers.
