After installing the desktop app (from WhatsApp website), users need to scan a QR code to log in. In order to use the new video calling feature, users will have to install the WhatsApp desktop app on either a Mac or PC, which requires that you already be a WhatsApp user on mobile. As mentioned, voice and video calls on WhatsApp Desktop are end-to-end encrypted. The new WhatsApp feature will work in both portrait and landscape orientations, and the video and voice calls appear in a separate resizable window. While WhatsApp calling does not directly compete against Zoom or Google Meet, the new feature has been highly anticipated by its massive userbase for over a year now.
The Facebook-owned instant messaging platform says that the feature is rolling out to users now and claims that similar to the voice and video calling on the mobile apps, the Desktop app also offers end-to-end encryption for calls. WhatsApp finally rolled out its highly-anticipated voice and video calling feature for the Desktop app last week.
