What is Two-Factor Authentication?
Two-factor authentication is an extra layer of security for your Apple ID designed to ensure that you’re the only person who can access your account, even if someone knows your password. It protects your account by requiring a password and access to either a trusted device or verification code delivered via SMS or phone call. Requiring more than just your password to access your account improves the security of your Apple ID and all personal information you store with Apple.
What is a Trusted Device and a Trusted Phone Number?
A trusted device is an iOS device or a Mac on which you’ve signed in with your developer Apple ID using two-factor authentication. It’s a device we know is yours and can be used to verify your identity by displaying a verification code from Apple when you sign in.
A trusted phone number can be used to receive verification codes by text message or automated phone call. You must verify at least one trusted phone number to enroll in two-factor authentication. This can be any type of phone number you use.
