WhatsApp has added a new and unique biometric authentication for its web and desktop application users.
This will definetly give a sigh of relief and peace of mind when they log on to the messaging service from their laptops or cellphones.
According to the company, all users will now be able to use fingerprint, iris, and face recognition when accessing WhatsApp Web or the WhatsApp desktop app alongside QR code authentication.

The feature will be enabled automatically on iPhones running iOS 14 and Android phones with biometric authentication enabled but can be turned off at the user’s discretion.
This new feature will help prevent other people from accessing private chats through the web browser in case they gain access to your phone.
