How to Enable Two-Factor Authentication on iPhone

With the latest trend in online security requirements, having a password is not enough to keep your iPhone account safe. If an unauthorized person obtains your password, you need another layer of security, specifically two-factor authentication. Two-factor authentication will ensure that your Apple account is safe and can only be used on trusted devices. When accessed from a new device, your account will ask for your account password and a six-digit verification code. The verification code will be displayed on your trusted devices. Furthermore, the verification code will be sent over SMS to your trusted phone number. Once the correct account password and verification code are entered, the new device will become one of your trusted devices. This tutorial demonstrates how to enable two-factor authentication on iPhone.

What is a Trusted Device?
A trusted device should be an Apple mobile device that runs on iOS 9 or later or a Mac with OS X El Capitan or later. Supported mobile devices are iPhone, iPad, and iPod touch. A trusted device should be already set up to use two-factor authentication – an indication that you own the device.

What is a Trusted Phone Number?
A trusted phone number is a mobile number that will be used to receive the verification code through SMS or a phone call. A trusted phone is required for you to enable two-factor authentication for your Apple account.
