How do I get rid of two factor authentication?

From the article below. If it has been on longer than 2 weeks, you can't turn it off. 

Can I turn off two-factor authentication after I’ve turned it on?

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, however, you can unenroll for a period of two weeks. Just open your enrollment confirmation email and click the link to return to your previous security settings. Keep in mind, this makes your account less secure and means that you can't use features that require a higher level of security.

I know for a fact that it can be turned off if the IOS is updated accordingly. Try your lies elsewhere.

If you already "know" it can be turned off, why did you come here asking if it was possible?

It cannot be turned off.

If I posted lies, how come when muguy posted it can't be turned off, you indicated that that solved your question?
