When attempting to log in to a new browser/app, you will have to open the mobile app and scan your face or fingerprint before you are able to scan a QR code, which links your device to a PC or laptop. So WhatsApp Web’s new biometric authentication lock is not quite the same as the on-device app lock, but it’s another safety net for those worried about third-party access. There is also the risk of someone simply scanning a QR code without your knowledge and having access to your entire chat history. Obviously, there are numerous privacy issues if your machine is accessible by multiple users.

Once this is done, it will remain logged in unless you specify otherwise. It appears as though this new feature will not simply “lock” WhatsApp Web unless you log out and then attempt to log back in.Īt present, the linking process simply involves scanning a QR code with no security process involved. The firm has said that from today, you will be able to add a fingerprint/face scan on Android or FaceID on iOS device that will lock the linking process between your smartphone and WhatsApp Web - or the desktop application. WhatsApp added biometric locking security to the mobile versions of the most popular third-party messaging app quite some time ago, but this is a first for the companion application - sometimes known as WhatsApp Web. To help boost your messaging security when using the desktop and web application, WhatsApp is planning on adding biometric security when linking the companion apps on desktop or laptop.
