How to link a device with phone number

You can now link a device using your primary account phone number and a one-time code. Up to four linked devices can be linked without the need to keep your primary phone connected. You'll need to log in to your primary phone every 14 days to keep linked devices connected to your WhatsApp account. For the best experience, update to the latest version of WhatsApp.
