OnePlus 6 Face Unlock Beat by Paper Printout

Think the OnePlus 6 face unlock feature is all the security you need to keep shady people from getting into your phone? Think again.

On Twitter this week, OnePlus 6 user Rik van Duijn, an ethical hacker with the Dutch security company DearBytes, showed it’s possible to beat the handset’s face unlock feature with a basic 2D printout of the owner’s mug.

“I printed my face to unlock my OnePlus 6 for the lulz… it worked,” he wrote. Check out how easy it is below.

van Duijn first attempted the hack with a color printout, then later tried a black and white image. Both worked.

OnePlus did not immediately respond to PCMag’s request for comment, but in a statement to Phone Arena acknowledged that its face unlock feature is more of a convenience thing, and isn’t secure enough for banking apps.

“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,” the company said, according to the report. “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.”

This isn’t the first time a smartphone face unlock system has been fooled. Shortly after the iPhone X hit the market last November, researchers at Vietnamese security firm Bkav Corporation said they were able to beat the phone’s Face ID feature using a specially designed mask. Tricking the iPhone X Face ID system is even easier if you look a lot like the handset’s owner, as one mother found out after discovering that her lookalike 10-year-old got into her phone with his own face.

The effectiveness of its face unlock feature aside, the OnePlus 6 earned an “excellent” rating in PCMag’s review.

“At first we were a little turned off by its $529 starting price, but the cult smartphone maker’s latest device won us over with its elegant software, a combination of Google apps and quiet, thoughtful additions,” PCMag’s Sascha Segan and Ajay Kumar wrote in the review.
