A new feature introduced by mark Zuckerberg on WhatsApp

Meta founder and CEO Mark Zuckerberg on Monday announced a new WhatsApp feature called ‘Chat Lock’ to make users’ most intimate conversations even more private.
This feature helps you hide your most intimate conversations with a password and secures them in a separate folder.
When a person texts you and you have that chat locked, the sender’s name and the message both are hidden. Zuckerberg’s announcement read, “We’re excited to bring to you a new feature we’re calling Chat Lock, which lets you protect your most intimate conversations behind one more layer of security.”
“Locking a chat takes that thread out of the inbox and puts it behind its own folder that can only be accessed with your device password or biometric, like a fingerprint. It also automatically hides the contents of that chat in notifications too,” he added.
