How to link a device to WhatsApp using a QR code

You can link your WhatsApp account to a second device using a QR code. This allows you to use WhatsApp on two devices at the same time, without having to keep your phone connected to the internet.

To link a device to WhatsApp using a QR code:

Open WhatsApp on your primary device.
Tap on the three dots in the top right corner of the screen.
Select Linked devices.
Tap on Link new device.
Scan the QR code on the second device.
On the second device, tap on Continue.
Enter the six-digit code that appears on your primary device.

Once the devices are linked, you can send and receive messages, make calls, and use all of the other features of WhatsApp on both devices.

Here are some additional things to keep in mind:

You can only link one secondary device to your WhatsApp account at a time.
The secondary device must be running Android 8.0 or higher or iOS 12.0 or higher.
The secondary device must be connected to the internet.
The secondary device must be within range of your primary device.

Iphone and Android:

You can now use the same WhatsApp account on multiple phones at the same time, using your primary phone to link up to four devices. You’ll need to log in to your primary phone every 14 days to keep linked devices connected to your WhatsApp account.
