In this case WhatsApp always requires a Wi-Fi connection, because it may use a large amount of your data plan: When the user wants to use WhatsApp on a second device, there is the need to copy the chat history.
WhatsApp is already working to create an interface on the Android app, as noted in this article and on WhatsApp for iOS: Actually they are testing the feature in order to work with 4 devices at the same time. Hopefully this latest news shows that we will soon get what we both want and need.As mentioned in these months, WhatsApp is working on the possibility to use the same account on different devices. As much as we want this new functionality, we need it deployed without risking our data security and privacy. Other messengers-including, of course, WhatsApp’s stablemate Facebook Messenger, have nailed multiple device access, but without the security we trust WhatsApp to provide. Much in the same way as you can tell when a contact has new device or WhatsApp install.Īnd, ultimately, that’s the most critical thing here. If, for example, any of the linked devices of one of your contacts changes or if they link a new device, then you will be notified. That is likely a step too far, without full control over the cloud and device software, as is the case with Apple’s iMessage and iCloud syncing.įrom what we know so far, it’s clear that WhatsApp’s considerable time spent in perfecting its approach to multiple device linking has encryption at its heart. This could provide the basis for a secure restore or even a secure live sync capability-although an ongoing sync would require that backup to be decrypted and accessed while at rest in the cloud, without compromising security. This backup update will essentially offload a secure, central repository of your message history and media to an offline cloud service.
