If, like me, you use the desktop version of WhatsApp, you know that it leaves a little to be desired when it comes to authentication. This is because just open the app, point to the QR code on the computer “et voilá”, you have access to all conversations. However, this is about to change.
Biometric authentication will be required to access WhatsApp on the computer
WhatsApp announced that turning on WhatsApp on your computer is now more secure with a small detail. This is because it will be necessary to do biometric authentication on the smartphone.

This means that, very soon, all users who want to access WhatsApp from their smartphone will have to unlock the app on their smartphone. This will be done using fingerprint or facial recognition.
Cited by The Verge, WhatsApp says that this novelty has as main objective that third parties who have access to your smartphone, cannot connect your account to their computer and thus have access to all your private conversations.
It is important to note that this measure will be implemented on any iPhone that uses iOS 14, either with Touch ID or Face ID. On all Android with biometric authentication, the functionality will also be active. This will only be disabled if you turn off this type of authentication from your smartphone.
It is important to note that this authentication measure does not give WhatsApp access to the facial recognition or fingerprint data you use. The update is expected to reach all compatible devices in the coming weeks. As of the writing of this article, it has not yet appeared in our tests.
