WhatsApp is rolling out a new security feature for WhatsApp Web and Desktop that lets users link a WhatsApp account to the PC or the web using biometric information. WhatsApp will use the same biometric authentication that is stored on the user’s smartphone. This means that users will be able to add in fingerprint or face recognition to use WhatsApp on desktop or web by linking it to their mobile app. The privacy feature will be used in addition to the existing QR code authentication. Of course, those who do not have biometric authentication enabled on their smartphone will not be able to use this new feature for the Web version.
The messaging app has clarified that it can’t access the biometric information stored by a user’s device’s operating system. Do note that the feature will work on iPhone devices running iOS 14 and above with Touch ID or Face ID, whereas, on Android, it will work on any device that is compatible with biometric authentication. Here’s how to use the face and fingerprint unlock when linking devices for WhatsApp Web and Desktop:
• Log in to WhatsApp on WhatsApp Web, WhatsApp Desktop, or Portal using the phone to scan the QR code.
• Open WhatsApp on your phone.
• Tap More options (for Android), while iPhone users need to go to WhatsApp Settings.
• Tap WhatsApp Web or WhatsApp Web/Desktop.
• Android users will need to tap LINK A DEVICE and follow the on-screen instructions. Make sure your biometric authentication is enabled.
• iPhone users will need to click on Tap Link a Device > OK. In this case, Touch ID or Face ID to unlock needs to be enabled.
• Select the checkbox next to Keep me signed in on the QR screen on your computer or Portal to stay logged in on this device.
• Use your phone to scan the QR code on your computer or Portal.
• If prompted, select Done.
