Information circulating the interwebs suggests that a users WhatsApp chats will be backed up across multiple devices once the multiple device feature is live. So if you like, you should be able to continue a chat from another device, once you are logged in on multiple devices. Recently it was reported that a user will be able to use his WhatsApp account across multiplied devices. The limit for these devices will be 4. It looks like when a user logs in on these devices, his/her chat will be backed up across all the devices.
Till now a user could use a WhatsApp account on a single smartphone. You do have the option to use WhatsApp for web by scanning a QR code on the desktop app via the mobile app to create the sync. The multiple device support will be across Android and iOS devices. According to wabetainfo, “When someone adds a new device in his WhatsApp account, you will be notified because encryption keys change”.
