WhatsApp is finally pushing an improvement to a key feature that even the Facebook-owned instant messaging service. WhatsApp said it is rolling out a limited public beta test for its improved multi-device capability.
The update enables WhatsApp users for the first time to use the service. On up to four non-phone devices without having the registered phone switched on or otherwise connected to the internet. Each companion device will connect to your WhatsApp independently.
WhatsApp, which is used by more than 2 billion users globally. Already provides support for multiple-device use. A user can simultaneously access the service, for instance, from a web browser or a desktop app on their computer. But the multidevice support flow currently requires the phone to be connected to the internet.
By requiring the phone to perform all operations, companion devices are slower and frequently get disconnected especially. When the phone has a poor connection, its battery is running low, or the application process gets killed by the phone’s OS. Each message is individually encrypted using the established pairwise encryption session with each device.
