Apple assures users that they value their security. However, there is a debate on whether or not Apple Face ID is secure. Apple states". The probability that a random person in the population could look at your iPhone or iPad Pro and unlock it using Face ID is less than 1 in 100,000 with a single enrolled appearance, whether or not you are wearing a mask. Apple warns users that the probability increases if they are wearing a mask, are a twin, have a sibling that looks like them, or are under the age of 13. Apple allows users to use a passcode to unlock their phones if they do not feel comfortable with Face ID. Apple also forces you to unlock your phone with a password if there are five failed attempts and allows you to only unlock your phone when your eyes are open. Apple affirms to users that "Face ID data, including the mathematical representation of your face, is encrypted and protected with a key available only to the secure enclave." It is easier to replicate touch ID through 3D printing than it is with Face ID. Face ID has also improved during the pandemic, as many people struggled to unlock their devices. You can now unlock your phone while wearing a mask, thanks to an improved Trudepth camera around your eyes.
However, some people argue that an intruder could easily unlock your phone simply by pointing the camera towards you. Even a friend or family member could easily unlock your phone, more so than the touch ID or password, and not many people are comfortable with that. The touch ID and the password require a bit more physical and mental work. Despite these concerns and the slight statistical increase that someone will open your phone if you are a twin, etc. Apple Face ID is generally known to be trustworthy.
