Will a picture of someone unlock Face ID?
No, you generally cannot unlock a modern iPhone or iPad with just a 2D picture because Face ID uses Apple's TrueDepth camera system to create a precise 3D depth map of your face, which a flat photo can't replicate. This system projects thousands of invisible dots and captures an infrared image, detecting depth and distinguishing real faces from photos, masks, or 2D representations, thanks to advanced neural networks. While some cheaper or older facial recognition systems on other phones might be fooled by photos, Apple's Face ID is designed specifically to prevent this.
