About Apple Account security questions
Two-factor authentication is the most secure way to protect your Apple Account. If you haven’t set up two-factor authentication for your account, Apple may use security questions to provide you with a secondary method to identify yourself online. Security questions are designed to be memorable to you, but hard for anyone else to guess. When used in conjunction with other identifying information, they help to verify that you’re the person requesting access to your account.
You may be asked to answer one or more of your security questions before you can change your password or other account information, view your device details or make a purchase in the App Store or other Apple media services on a new device.
If you don’t want security questions or you’re concerned about forgetting the answers, you can set up two-factor authentication. Find out about two-factor authentication.
