As we reported earlier, WhatsApp was testing a multi-device support feature. Now, the feature is finally rolling out to the non-beta testers with the latest update. The Multi-Device Support allows the users to use WhatsApp on four devices apart from their Android or iOS smartphone. To mention, this does not sacrifice end-to-end encryption, thus ensuring privacy and security.
Also, keep in note that the function can be used only on non-phone devices that include, WhatsApp Web, WhatsApp Desktop, and Portal. The multi-device functionality is moving from beta to stable phase of WhatsApp version 2.21.19. Reportedly, the app will “force users to update to the multi-device version, for a future update.”
Interestingly, the user can operate the app without having an internet connection on the primary device. That implies the second device will work independently. Moreover, the user can also switch off the smartphone and still use WhatsApp on the connected device uninterruptedly.
If you were using Multi-Device Support under the beta program, follow the below steps to join or leave the functionality based on your platform.
