On Monday, Meta CEO Mark Zuckerberg announced the launch of its new security feature: Chat Lock. This helps user protect their most private conversations with a password.

As per the new feature, the locked chat will vanish from the inbox and gets hidden in the 'Locked Chats' folder. The folder itself can be accessed with your device password or biometric, like a fingerprint.

"Chat Lock joins WhatsApp’s growing list of privacy features that users can take advantage of, including end-to-end encryption and encrypted backups, disappearing messages, screenshot blocking, controls over who can see when you were last online and more," the messaging platform added.

"We think this feature will be great for people who have reason to share their phones from time to time with a family member or those moments where someone else is holding your phone at the exact moment an extra special chat arrives," the company said in its blog post. 

The chat can be locked by tapping the particular conversation and selecting the lock option. Once locked, the sender’s name and the content of the message will also be hidden. To reveal the chats, one can enter your phone password or biometric.

The company added that they would be bringing in new updates over the next few months for Chat Lock. These include locking companion devices and creating a custom password for chats so that one can use a unique password different from the one you use for your phone.

WhatsApp had added a few new updates around polls and sharing with captions. As part of these updates, create single-vote polls, search for them in chats and receive notifications when people vote on polls.

The new updates also help one forward media with captions, or add captions to documents when sharing as a context.
