With numerous helpful features, WhatsApp is once again working on a new privacy feature that will enable users to open WhatsApp Web only with a biometric authentication. The feature is currently under development and limited to beta testers.
Wabetainfo, spotted this new functionality on WhatsApp Beta for Android version 18.104.22.168. The update also brings some bug fixes for Recently Used Emojis alongside the new fingerprint feature.
This fingerprint authentication system will ensure that your WhatsApp chats are safe on the desktop and create a layer of complete security for the users.
To use WhatsApp on desktop or PC, users need to currently scan the QR code displayed on WhatsApp web, but soon they will be required to use the fingerprint scanner to successfully use WhatsApp on desktop.
WhatsApp fingerprint lock system works in the same way as the fingerprint lock of any smartphone does. It enables users to protect their conversations from intruding eyes of strangers. The feature was recently added in the Settings option and available for both Android and iOS users.
To enable fingerprint lock on WhatsApp: tap Settings, go to Account, then Privacy and Fingerprint Lock. You can then turn on Unlock with fingerprint, and confirm your fingerprint.
Moreover, WhatsApp also introduced a new animated sticker pack called Usagyuuun in the default sticker list recently. This pack has a white cartoon character that depicts feelings of joy, anxiety, sadness, love, etc.
WhatsApp is also working on a new feature called Wallpaper Dimming. This feature will let users adjust the opacity of the wallpapers in WhatsApp. However, it will come in the wallpaper section which is still in the works.
