Each linked device (four devices can be linked) will work independently, and even when there is no network access on the primary device, the independent devices will continue to receive messages. Note that if the primary device is inactive for a long time, WhatsApp will automatically log out on all the companion devices. Four additional devices could include four smartphones or a combination of PCs and smartphones.

Here’s how to link companion smartphones to WhatsApp.

This can be done in multiple ways, and Meta has confirmed to release more ways of adding companion devices. Right now, one needs to enter the phone number on the secondary phone and then enter the OTP received on the primary device. Similarly, one can also add a companion device by scanning the code on the primary device.

This will allow users to have a WhatsApp account on an Android or an iOS device and then add a companion device, which can be an Android or an iOS device. Meta has confirmed that the update is rolling out across the world and should reach all devices in the coming weeks.

To get this feature, make sure to download and install the latest version of WhatsApp on your Android and iOS devices. Also, note that both primary and companion smartphones should have up-to-date WhatsApp to use this feature.
