Last year WhatsApp announced multi-device support. Details of this feature are now being worked out.

Multi-device support is available to some WhatsApp beta users and is not yet available to all users. However, thanks to WABetaInfo, we can get a glimpse of the multi-device support.

This new feature, officially called "Linked Devices," allows you to link new devices to your account. This will allow you to access your WhatsApp account from anywhere you like, including your desktop, browser, and Facebook Portal smart display.

Unfortunately, WhatsApp has only updated the user interface, so users cannot try this feature yet. In other words, the changes are purely visual for now, and one must go to the settings menu to notice any changes.

In any case, it will be interesting to see how WhatsApp handles multi-device support. Messages are stored on the device, not on WhatsApp's servers, so they are not automatically synced every time you update to a new device. [It is also possible that WhatsApp sends all messages to the active device or acts like a WhatsApp web client, which is a mirror of WhatsApp with a link is required. This means that if the "Prime" device's battery runs out or it is disconnected from the Internet, access to WhatsApp will be blocked.

We have not yet determined when Linked Devices will be released in beta or stable. Given that we first glimpsed it in October and little has changed in the months since then, it may be a while yet.
