A Twitter user @rikvduijn yesterday posted a video of the OnePlus 6 being unlocked with a paper cutout of his face. Worst of all? The method apparently works with a black and white photo as well.
In the video, you can see (below) one of Rik’s friends holding a photo of his face—just a selfie, judging by the wide-angle appearance of the image—and showing it to the OnePlus 6, which almost immediately (and terrifyingly) grants him access to the OS.
Well, it turned out that OnePlus was wiser than that and actually employed their own custom solution, developed by a Chinese security company called SenseTime, that has a sizeable background in facial recognition.
I printed my face to unlock my OnePlus 6 for the lulz… it worked ¯_(ツ)_/¯ pic.twitter.com/rAVMq8JKBr

“We designed Face Unlock around convenience, and while we took corresponding measures to optimise its security we always recommended you use a password/PIN/fingerprint for security. For this reason Face Unlock is not enabled for any secure apps such as banking or payments. We’re constantly working to improve all of our technology, including Face Unlock.”
