I recently wrote an article on how to turn on Two-Factor Authentication on your iPhone for better security. Apple introduced this feature in iOS 10 And then, with the release of iOS 11, iPhone users were automatically upgraded from Apple's less secure Two-Step Verification feature. Apple ID Two-Factor Authentication requires the use of multiple devices. For example, if you get a new iPhone, when you log into your Apple ID account for the first time, you’ll need to use your Mac, iPad, or old iPhone to receive a six digit Apple verification code to confirm that it’s you logging in and not some stranger trying to access your account on a random device. This is important since your Apple ID is used for everything from storing personal photos to making purchases with your credit card. However, if you don’t feel the need to use this feature, you can use this tip to turn Two-Factor Authentication off. Be careful though, your Apple ID account wil be significantly less secure and you may not be able to use Apple Pay Cash and other Apple features when you turn off Two-Factor Authentication.
