How the new WhatsApp feature that makes the app more secure works
While many users give up WhatsApp For privacy reasons, application developers are releasing an update that will make a crucial and so far not very secure step in using the system more secure: theadding a new computer to the list of devices authorized to use WhatsApp Web. The feature will launch and ensure that users have to choose one. biometric proof of your identity before activating WhatsApp Web on a new device.
The WhatsApp web interface is very convenient to use the messaging service in front of the computer, but the internal chats are a carbon copy of those stored in the phone; Therefore, there is no doubt that the system poses a threat to the security of user data. On the one hand, the system is intrusion-proof and there is no known risk that hackers could sneak into chats using the web interface; on the other hand, to connect a WhatsApp profile to a web session, simply point at smartphone camera on the screen to open the browser to the corresponding page. The operation takes fractions of a second and connects the two devices indefinitely.
In short, the risk is that a close person, trusted or not, takes advantage of a moment of distraction from a potential victim to secretly steal your smartphone, link it to a nearby computer, then send it back as if nothing happened; the result would allow anyone with access to that computer to continue monitoring the victim’s chats. To be fair, in WhatsApp there is a function that lists all open and active web sections, but the information reported They are not for everyone.
The solution: secure biometric verification
That is why the WhatsApp developers have decided to add a security measure to the process of activating a new WhatsApp web session. Once you have chosen the appropriate option, before activating the camera to pair the phone with the browser will present the biometric unlock interface, for example, when you wake up the device from standby mode. It does not matter if it is the fingerprint under the screen, a fingerprint reader on the body or the Face ID of the iPhone: the operating system takes care of the recognition of the rest. WhatsApp doesn’t handle any verification aspect nor does it store biometric data of the user. Once the owner is recognized, it is possible to frame the QR code displayed on the WhatsApp web page open on the computer and end the connection between the two devices.
The novelty is being released, this is the reason why it may take some time for it to be available on all smartphones. Forcing the update from the Play Store and App Store might speed up the process, but the wait shouldn’t be long anyway.
