Users of WhatsApp now have the option to lock particular chats using a password or biometric authentication according to a new feature introduced by Meta.
On both Android and iOS, it has been possible to lock the entire WhatsApp app using biometrics or a PIN number, but this new capability enables users to further protect particular private messages.
The chat-locked messages will therefore stay private even if someone gains access to your phone. Without a code, nobody can open.
End-to-end encryption, encrypted chat backup, and vanishing messages are just a few of the security and privacy-related capabilities that WhatsApp already offers.
Among other things, you can limit who can see the last-seen status and block screenshots. With the most recent version, Meta has improved WhatsApp's privacy and security features even more.
