WhatsApp offers Locked Chats: Extreme Privacy for your chats
WhatsApp has announced Locked Chats feature which will offer extreme privacy for your chats.
Ever since WhatsApp had some problems regarding privacy and security couple years ago, the application started to offer more privacy features. A new feature called "Chat Lock" will be added to WhatsApp to make it easier to keep conversations private. The new locked chats will reside in a folder protected by password or biometrics, and notifications from those conversations will not display the sender or the content of the message. Assuming you knew all about Apple's covered up photographs highlight for iCloud, Visit Lock seems like it will work much the same way.

Although WhatsApp is already well-known for its end-to-end encryption of messages, this will not prevent someone with access to your WhatsApp-enabled, unlocked phone from potentially reading a message. If you frequently need to share your unlocked phone with someone this feature will help you keep your chats private.
Chat Lock is now available, and there will be further enhancements in the near future. Meta wrote in a blog post, "Over the next few months, we're going to be adding more options for Chat Lock, including locking for companion devices and creating a custom password for your chats so you can use a unique password other than your phone's."
