What is Always-on Face ID?

Always-on Face ID is like having a special face scanner that works all day long without you needing to touch your phone.

Imagine your phone has eyes, super smart eyes that can see you even when the screen isn’t on. These eyes are always watching, just like how you might watch your favorite toy from across the room while playing with something else. When you look at your phone, these smart eyes recognize your face and let you unlock it instantly, no need to type a password or press any buttons.

How It Works

Think of it like this: Your phone has a camera that never sleeps. This camera takes pictures of your face in the background while you’re using other apps or just sitting there. When it sees your face, it knows it's you and wakes up the screen so you can use your phone right away.

It’s kind of like having a friend who always knows when you're near, they don’t need to ask you every time, they just know. That’s how Always-on Face ID works: it knows you’re there, and it makes things easier for you!
