Certain Apple services and features, such as Apple Pay and Sign in with Apple, require two-factor authentication. Two-factor authentication is the default security method for most Apple IDs. Because just knowing your password isn't enough to access your account, two-factor authentication dramatically improves the security of your Apple ID and the data that you store with Apple. 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. 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.
