WhatsApp now allows multiple phone usage for one account.
WhatsApp now allows users to log into their accounts on multiple smartphones, in addition to tablets, computers, and browsers. Users can link their accounts by scanning a QR code on their primary device. WhatsApp treats the original smartphone as the "primary" device, but users can switch to a new primary device by downloading a fresh version of the app and logging in with their phone number. The feature has been highly requested by users.
