WaBetaInfo claims that this new feature would enable users to password-protect the desktop version of the app.
The screen lock option was previously only available to Android and iOS beta users, but WhatsApp is currently working on a fix to make it available to PC beta users as well.
As seen in the above screenshot, users will be required to provide a password each time they launch the application. For those whose computers are shared, this is helpful.
The WhatsApp news tracker stated: “Note that using this feature is optional and likely, the user will have more control over it by choosing when the app should demand the password.”
Additionally, because the password is always saved locally, WhatsApp won’t know it. If a user forgets or loses their password, they will need to log out of the app and re-log in to the desktop by scanning a QR code on their mobile device.
This feature is not available as of yet as it is still being developed. It will be released in a future update.
“As additional news, WhatsApp may also implement a feature that lets users lock the app by using Touch ID on a Mac when a fingerprint sensor is available,” it added.
