WhatsApp’s beta program has finally reached a wide rollout across iOS and now allows all users on the latest version of WhatsApp to access the multi-device option. The new feature brings support for using one WhatsApp account across up to four devices including a macOS/Windows computer, a Facebook Portal, or a device running a WhatsApp Web session. Sadly you still cannot link a secondary phone to your main account.

Users on the latest 2.21.180.14 version of WhatsApp for iOS who’ve enrolled in the beta program will now get a multi-device prompt under the Linked Devices section within Settings. The big addition of using multi-device support is that you don’t have to keep your phone online. Adding a new device happens via scanning a QR code with your phone just like on WhatsApp Web.
The time it takes to link a new device will reportedly vary based on your message history size. As with all beta software, WhatsApp warns that some features may not work properly or may come with some issues.
