WhatsApp now lets you use secret codes to lock your private chats

WhatsApp is making its Chat Lock tool even more secure by introducing secret codes that hide private chat rooms.

The way it currently works, Chat Lock takes conversations and places them in a separate folder that can only be accessed with your phone’s password or a biometric login. This can be useful if you share the device with others. However, it doesn’t stop other people who know the password from taking a look at any time. Secret Codes addresses this by allowing users to implement a second password, separate from “what you use to unlock your phone”. Creating one, according to WhatsApp’s announcementmakes your locked folder disappear from your inbox as an extra layer of privacy.
