Face unlock checks who you are, not what you want.

A man went up to a room at Harrah's, one of the Atlantic City hotels. Police say two women held him down and used his face to open his phone.
The phone saw a real, <phoneme alphabet="ipa" ph="laɪv">live</phoneme> face and said yes.
Face unlock checks who you are, not what you want.
According to Hoodline, police charged two women in October. Police say twelve hundred and fifty dollars left his Apple Pay. These are charges, not convictions.
Phone makers build checks to catch photos and masks. They can't catch a real face held by someone else. For investigators, a forced yes looks like a willing yes.
Your face can open your phone. Your face can't say no.
One phone trusted a face too easily. Australia's apps can't even tell who's grown up.
Picture a mom in Sydney opening an app. It says she looks too young and wants her license.
Australia banned social media for kids under sixteen. Now it's suing Facebook, Instagram, TikTok, Snapchat and YouTube. Age verification means proving your age to get in.
Kids slip through while grown-ups get stuck.
According to NBC News, a software test opened fifty accounts after the ban. None were asked for proof of age.
Zero for fifty. When a check wrongly flags an adult, the fix is more personal data. A passport. A closer face scan. For lawyers, the law says 'reasonable steps' but never names them.
A broken check doesn't fail quietly. It asks for more of you.
Those apps ask for your face. Your photo app never asked at all.
A dad taps his daughter's face in Google Photos. Every picture of her pops up.
That's Google face recognition, working quietly in the background. It turns each face into a list of numbers. Then it piles <phoneme alphabet="ipa" ph="kloʊs">close</phoneme> matches together.
Google Photos keeps a number code for every face.
According to Google Photos Help, those codes stay until you delete them. Or until your account sits unused for over two years.
One switch, called 'group similar faces,' deletes the codes, piles and names. Your photos stay. For investigators, a face pile is a guess to check, not proof.
Your switch covers only your account. Your face in a friend's photos has no switch you can reach.
A face opened a phone for someone else. An app wanted a face to prove an age. A photo app filed faces without asking. Each time, the tech worked as built. Your face is a key now. Know who's holding it.
