All users now have access to the new Chat Lock feature through the user’s profile page, which was made available by WhatsApp to all users. Anyone can now lock specific WhatsApp chats so that no one else can access them with the new version. This feature will be useful if you have to give a stranger your smartphone for work purposes and don’t want them to read your private chats. With the new WhatsApp Chat Lock feature, which also automatically hides the contents of the chat in notifications, your privacy is protected. The new message is not visible when you launch the applications since it is kept in the Locked folder. As a result, your privacy is safeguarded.
