Use WhatsApp on four devices with Companion Mode: Here's how

Want to use the same WhatsApp account on more than one phone? Here’s how Companion Mode works.

Install WhatsApp on your second phone and open the app.

On the number screen, tap the three-dot menu and select Link as companion device.

A QR code will appear on your second phone screen.

Open WhatsApp on your primary phone and go to Settings → Linked Devices.

Tap Link a Device and scan the QR code from the second phone.

Once linked, your chats will sync automatically across both devices, which you can use without keeping your primary phone online.
