What is Face ID and how does it work
Face ID uses special hardware in your iPhone to create a detailed 3D map of your unique face and compares it every time you look at your phone. It's extremely secure because your face data never leaves your phone — Apple can't see it, and neither can anyone else.
Face ID is a biometric security system on modern iPhones. When you set it up, your iPhone's special camera creates a detailed mathematical map of your face's unique features: the distance between your eyes, your nose shape, cheekbone contours. This data never leaves your phone — it stays encrypted only on your iPhone. Every time you look at your phone, Face ID instantly compares your current face to that stored map.

Common mistakes to avoid
- Thinking Face ID sends your face photo to Apple — it doesn't. Only a mathematical map stays on your phone.
- Confusing Face ID with fingerprint — they're two different systems.
- Thinking Face ID can be fooled by a photo — it uses 3D depth mapping, not facial image recognition.
