Many iPhone users fear that someone will access their mobile phones through a simple trick, by hacking the facial recognition feature to reveal text, photos and videos.

According to a report by the British newspaper "Daily Mail" that the "True Depth" feature in the iPhone camera can scan accurate facial data by analyzing thousands of invisible points, so that it draws all the curves and wrinkles of the user and stores that data as a key to unlock your phone.

Face recognition automatically adapts to changes in your appearance, such as applying makeup, growing facial hair, or even wearing a face mask.

If there is a more significant change in your appearance, such as a beard shave, facial recognition confirms your identity using your passcode before updating your facial data.

Apple claims that there's a one-in-one million chance that someone else can unlock your iPhone, but what about using your face?

It is a common fear that someone picks up your phone and puts it in front of your face while you sleep to unlock it, and it seems that these systems do not work if your eyes are closed, but there is a way to bypass this protection built into your iPhone, smartphones come with features to enable people with visual, hearing or mobility impairments to access their phones without having to look at them.

Assistive Touch helps to use the iPhone if the user has difficulty touching the screen or pressing buttons.

These are essential tools for people who need them, but one of these settings may put your security at risk, as facial recognition also has an accessibility feature to support people who are blind or have low vision, and with this setting you will not need to open your eyes to unlock your phone.

While some people need these features, you shouldn't use it if you don't have low vision, so you should adjust these settings by following these steps:

  • Go to Settings and then to Accessibility and then Face & Attention ID.
  • Make sure that "Require attention for facial recognition device" is turned on.

When this setting is turned on, no one can unlock your phone while you sleep.
