WhatsApp is adding an extra layer of security for logging into WhatsApp web and desktop app.

According to the messaging app, the security is designed in a way that would authenticate the face and fingerprint of users on their devices in a privacy preserving manner.

In order to link WhatsApp Web or Desktop to the users' WhatsApp account, they will now be asked to use their face or fingerprint for unlocking, before scanning a QR code from the phone to link their devices.

As millions of people now access WhatsApp on their PCs and laptops, the biometric authentication feature is rolling out to both Android and iOS users.
