And it happened… A security firm has managed to trick Apple’s innovative Face ID with a 3D mask specially designed to fool the facial recognition system. Security firm Bkav wrote that while others have failed at successfully tricking Face ID, their mask worked because they understood “how AI of Face ID works” and then used that information to bypass it.

“The mask is crafted by combining 3D printing with makeup and 2D images, besides some special processing on the cheeks and around the face, where there are large skin areas, to fool AI of Face ID.”
