How To Turn Off 2 Factor Authentication Iphone

Two-factor authentication (2FA) is a secondary security measure that provides you with an access code for your Apple ID after you enter your username and password on a new device or into iCloud.com. Apple allows its customers to set up 2FA for their iCloud accounts on the best iPhones and best iPads, and get codes from a circle of trusted devices which also include Macs.

Bottom line: If you want something more than just your password to protect your Apple ID — which you use for iCloud, iTunes, and the App Store — then you want 2-factor authentication turned on.
