Migrate Your Apple ID to Two-Factor Authentication from Two-Step Verification

Apple ID offers several authentication methods, including:

  • Two-Step Verification
  • Two-Factor Authentication

While these terms sound similar, they refer to distinct methods. Many web services offer two-step authentication to safeguard accounts. However, two-factor authentication, a more secure option, is required for certain Apple Services.


Understanding Two-Step Verification

Two-step verification, akin to methods used by other web services, involves registering your mobile number and receiving a one-time code via SMS.

You will get a 4-digit code through SMS when signing in with your Apple ID. Enter this code on the waiting page to complete the sign-in process.

The Advantages of Two-Factor Authentication

Two-factor authentication, integrated into the operating system, offers enhanced security. Requirements include:

  • iOS 9 or later
  • OS X ElCapitan (macOS 10.11) or later

Additionally, a mobile number capable of receiving SMS and a trusted device is necessary.

Migration Process

To migrate, sign into your account on an operating system supporting two-factor authentication. A message will prompt you to begin the migration. Follow these instructions. The process may take some time, and you will receive email updates on its progress.

For Infrequently Used Apple IDs

You might worry about receiving the one-time code if you seldom use your Apple ID. However, our testing confirmed that receiving the SMS code is still feasible.
