WhatsApp, which will soon implement a revised privacy policy that allows it to share information with Facebook, says it won’t have access to your biometrics at all and will conduct the authentication process through your phone’s OS.

The new biometric authentication feature is active by default, and the only way not to trigger it when linking your account is to completely switch off face or fingerprint unlock.

As long as the phone you’re using has face or fingerprint unlock switched on, WhatsApp will ask you to go through the authentication process when you link your account to the service’s desktop app or web version.Īfter the service verifies your identity, you’ll then have to scan a QR code with your phone. The Facebook-owned company has added a layer of protection to its apps in order to limit the chances of somebody else linking to your account without your knowledge or permission. You’ll now have to confirm your identity using your biometric information to link a WhatsApp account to the PC or the web.
