Dear Mr/Ms
Now I'm using Iphone 7+ 32Gb with IOS version 13.6.
Before that I have turn on two-factor authentication for my iphone and now I want to turn it off but cannot. I would like to have your support to turn off it.
And one more question: After I turn it off, how long I can turn it on again?
Thanks and best regard,
iPhone 7 Plus, iOS 13
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, you can unenroll within two weeks of enrollment. 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 higher security.
