Hide and password-protect your private conversations with Secret Code for Chat Lock in WhatsApp
WhatsApp has launched a new way to help protect your sensitive conversations, extending the capabilities of Chat Lock which rolled out earlier in the year.
The newly added feature makes it possible to both password-protect and hide those chats you don't want anyone else to see. These hidden conversations can only be accessed by those who know of their existence and who have the necessary code to make them visible.
