WhatsApp is changing the way some account logins work Facial recognition

WhatsApp is adding an extra layer of security to its desktop and web apps, requiring users to use their phone’s face or fingerprint scanner in order to log in.

At the moment, users can log into WhatsApp on the desktop by simply using their phone to scan a QR code on the computer screen. You can only be logged into one device at a time, so doing this will automatically log you out of the app on your phone.
