On January 28, 2021, WhatsApp announced that it will roll out new Biometric Features. These features will allow the user to log into the account through a face ID or fingerprint authentication.
The update is not available in all regions just yet, but once it arrives, WhatsApp says you’ll be able to toggle on the extra security from within the app’s privacy settings menu. You can also let the app remain unlocked for one or 30 minutes after you unlock it. In addition, there’s also a toggle to prevent the contents of your messages from appearing in notifications.
In a recent Tweet, WhatsApp shares how the new security features will be available for WhatsApp Web and Desktop as well.
Today we’re starting to roll out a new security feature for WhatsApp Web and Desktop: face and fingerprint unlock when linking devices.
WhatsApp does not see your face or fingerprint data.
