WhatsApp already allows you to keep the Android or iOS app password-protected. You can also unlock the app using facial recognition or a fingerprint scanner. In addition, we may soon see a similar feature on WhatsApp’s desktop version to provide added security. Earlier, WhatsApp beta rolled out a companion mode and support for Android tablets.
WhatsApp is adding security features for desktop users
According to a recent report by WABetaInfo, WhatsApp will soon add the Screen Lock feature to its desktop version. Every time you access WhatsApp on your PC, the new Screen Lock feature will prompt you to enter a password. So, if someone else is using your desktop, this will help you keep your WhatsApp chats secure.

The report includes a screenshot of what this will look like. But since the feature is still being worked on, some parts of the user interface are missing right now.
It has been revealed that the passwords used to unlock WhatsApp on a desktop will not be shared with the Meta-owned messaging platform but will be stored locally. As an added feature, the feature will include fingerprint scanning on a Mac.
If you forget your password, you can recover it by logging out of WhatsApp and logging back in via the desktop client. This can be accomplished by scanning the QR code with your smartphone.
Availability
This feature is currently being tested as part of the WhatsApp for Desktop beta. The Screen Lock feature is in development, so there is no word on when it will be available to everyone.
