Video Security researchers have once again claimed a simple mask to hoodwink Apple's Face ID authentication system that graces the tech giant's $1,000 iPhone X.

Earlier this month, bods at Bkav, based in Vietnam, demonstrated it was possible to bypass the face-recognizing login mechanism using a $150 3D-printed mask, effectively allowing a stranger to unlock a victim's handset.
