WhatsApp is one of the most famous messengers, offering end-to-end encryption, yet it falls short on its other safety features compared to competitors like Telegram.
However, Meta, the parent company of WhatsApp, seems to be changing this in recent times. Some months ago, it added the ability to require fingerprint authentication to open WhatsApp and to use WhatsApp Web, and it also added the ability to encrypt the WhatsApp backup on Google Drive.
Continuing the path of adding useful features, it’s being reported in a new report via WABetaInfo that in the new WhatsApp update, users will be able to lock particular chats via their personal fingerprints.

Other than this, not much information is known at this moment, like how many chats we will be able to lock, how notifications from these chats will appear, and how the media from these chats will be stored.
More details regarding the development of the features will continue to emerge over the course of time. Be sure to stay tuned to get the latest updates.
