WhatsApp multi-device support is not new for us. For some years, the company is working on this feature, and some days back we came to know that the messaging app has started public beta testing of Multi-Device Support. Till now, if we wanted to use WhatsApp web on our desktop, we needed a device that is powered on and connected to the internet however now a WhatsApp multi-device Beta test supports multiple devices without an active phone.
This feature took very long to reach us and in June WhatsApp Head, Will Cathcart and Facebook CEO Mark Zuckerberg revealed that this feature is quite challenging as they also have to keep in view end-to-end encryption.

He shared images showcasing WhatsApp Message Architecture:
