A screen found in a previous beta showed that devices could be getting the ability to sync recent messages, even though they’re end-to-end encrypted. That screen, combined with the “Register Device as Companion” screen that instructs users on how to use WhatsApp on another device, adds up to compelling evidence that this feature is in the works.

"WhatsApp users can already link a phone and a computer"

Both screens have been found in the Android version of the app, which implies that the feature will support chatting on a secondary phone or tablet. At the moment it’s unclear if the feature will also be available on iOS if and when it launches, though there is precedent indicating it will. WhatsApp technically supports using your account on multiple devices already, via the Linked Devices feature, which currently only supports using computers as secondary devices. The feature is available on both iOS and Android.

WhatsApp rolled out Linked Devices as a public beta in November 2021, and has improved on it since then (though there are still a few unsupported features, depending on what your main device is). But while Linked Devices is handy for desktop users, it doesn’t do much for those with secondary smartphones or tablets. Meta, WhatsApp’s parent company, didn’t immediately respond to The Verge’s request for further details on its plans to expand the Linked Devices feature to support mobile devices as well.
