There is a flaw to the Samsung Galaxy S8 that is worrisome for end-users. After the Galaxy Note 7 battery issue, this latest Samsung offering has a lot to live up to. According to many reviewers it has exceeded expectations for the design and functionality, but not for security.

Reviewers of the phone have found a security flaw with the facial recognition authentication. This feature allows you to unlock your phone with the front-facing camera. The facial recognition feature can be tricked with a physical photo. Several reviewers unlocked the phone with printed and on-screen images of themselves.

This is alarming as smartphone security is growing more and more crucial due to the sensitive personal information they contain. Today, a smartphone stores banking data, home addresses, passwords to sensitive accounts, and so much more. The risk of this information being accessed is increased when the facial recognition feature is used to unlock the phone.

In a statement to Business Insider, Samsung shared that, “Facial recognition is a convenient action to open your phone – similar to the ‘swipe to unlock’ action… We offer the highest level of biometric authentication – fingerprint and iris – to lock your phone and authenticate access to Samsung Pay or Secure Folder.”

During initial set-up there is a warning that the facial recognition is not as secure as other authentication options. We recommend not enabling this feature to ensure security for your phone.

Instead, use the iris scanner, provided by Princeton Identity, as it is a secure option. The iris authentication for Galaxy S8 scans 200 points of your iris during setup. In a statement Princeton Identity provided CNBC, they stated that the iris scanning technology is 100,000 times more resistant to false positives than facial recognition.

Don’t risk your security, disable your facial recognition feature to protect your devices.
