Meta CEO Mark Zuckerberg has unveiled a new security feature called “Chat Lock” for WhatsApp to enhance user privacy. With Chat Lock, users can protect their sensitive conversations by setting a password.
The locked chats will disappear from the inbox and be stored in a dedicated “Locked Chats” folder, accessible only through the device password or biometric authentication. This feature complements WhatsApp’s existing privacy tools, including end-to-end encryption, encrypted backups, disappearing messages, and more.
Meta plans to introduce updates for Chat Lock, including locking companion devices and setting custom passwords for individual chats. WhatsApp has also rolled out updates for polls and sharing, allowing users to create single-vote polls, search for specific polls, and receive notifications when others vote.
Additionally, media can now be forwarded with captions, and captions can be added to shared documents. These developments reinforce Meta’s commitment to user privacy and a seamless messaging experience on WhatsApp.
