Apple has previously introduced two- step verification to unlock your Mac. But most recently Apple has introduced 2 factor authentication ( 2FA ), a more secure method that ensures maximum security. Even if someone knows your password he/she can’t access your iCoud, iTunes or any of your Apple devices. When you want your system to be more protected not just protecting it with the password then 2FA is the best option available.
How it Works
Whenever you want to login to your device the 2 factor authentication generates a onetime 6 digits code in one of your devices. The 2FA requires an Apple watch for auto unlock macOS. You will be required to enter the 2FA code whenever you want to login to Apple ID, iCloud, iTunes, iBooks, FaceTime, game centre or you want to make any purchase from App Store.
Disable Two Step Verification
The 2FA is required to enable on your device to use it using 6 digits verification code. When you already have two-steps verification, you have to turn if off to enable the new 2 factor authentication. You can turn if off by following the steps below.
- Go to applied.apple.com.
- Enter your Apple ID and Password.
