iOS 15.4's Face ID With a Mask Feature Requires iPhone 12 or Newer

Apple added a useful new feature that changes the way Face ID works in the latest version of its operating system. The Face ID with a mask option allows the phone to be unlocked if you wear a mask, but you need to have an older phone.

If you have an Apple Watch for security, you can use a mask to unlocked the phone, but the new option removes the need for an Apple Watch. Face ID with a mask works by recognizing the area around the eye, which is less secure but more convenient.

Unfortunately, Face ID with a mask is limited to some of Apple's newest phones, even though Face ID has been available for some time.

You will not be able toggling on the Face ID with a mask option in the settings app if you have an older version of the phone.

It is not clear why Apple has limited Face ID with a mask to the newer models of the device, but there may be some differences in Face ID hardware over the years that allow it to work for some devices and not others.
