Two-factor authentication is an extra layer of security for your Apple ID, designed to make sure that you're the only one who can access your account-even if someone else knows your password 1 . When you sign in with your Apple ID for the first time on a new device or on the web, you need both your password and the six- digit verification code that's automatically displayed on your trusted devices 1 . A trusted device is a device that you've already signed in to with your Apple ID and that can receive verification codes 1 . You can also add or remove trusted devices and phone numbers from your Apple ID account page 1 . Two features of two- factor authentication for a personal Apple ID are:
* It ensures that only the account's owner can access the account. This is because you need to verify your identity with both your password and a verification code that is sent to a device or phone number that only you have access to 1 . This prevents unauthorized access to your account even if your password is compromised or stolen 1 .
* It can be accessed on trusted devices. This means that you can sign in to your Apple ID account on devices that you've already verified with two-factor authentication without needing to enter a verification code again 1 . This makes it easier and faster to access your account on devices that you use frequently and trust 1 .: 1 : Two-factor authentication for Apple ID - Apple Support.
