This means that the user has to go through a biometric security layer such as a fingerprint scanner or Face ID before accessing the WhatsApp account on the computer or laptop on the web or the app. WhatsApp has said that the new security layer will be rolled out in the coming days. Also, a visual redesign of the WhatsApp web page will be offered for the phone.
How to use it?
What would the benefits be?
After the introduction of the biometric security layer of WhatsApp, no one will be able to use WhatsApp incorrectly on a computer or desktop. If your WhatsApp account is left open on the computer and desktop, even then the user would have to enter the biometric information to access the account again increasing the security of the data.
Currently, if your WhatsApp account is logged in on the laptop or desktop and if you shut down the laptop; then, when someone turns on your laptop, they will be able to access your WhatsApp account without any security layer.
