Wow!
The probability that another person in the population could look at your iPhone or iPad Pro and unlock it using Face ID is approximately 1 in 1,000,000 with a single enrolled appearance.
The statistical probability is different for twins and siblings that look like you and among children under the age of 13, because their distinct facial features may not have fully developed.

If you're concerned about this, Apple recommends using a passcode to authenticate.
