How to use WhatsApp on a secondary device without keeping phone online
Meta-owned company recently released a new update to both Android and iOS versions of WhatsApp (including WhatsApp for Business), that will enable users to link their messenger app account to multiple devices.
The important aspect of the new update is that it directly opts users to join the multi-device beta program. With this, users will be able to link up to four devices and one phone only.
Another interesting thing is that while linking the secondary device, the phone need not have to be connected to the Internet. Previously, while opening or operating the WhatsApp Web on the desktop, the phone had to be connected to the internet at all times.
