How to link WhatsApp to another phone or device

Linked devices are a full copy of your account. How to link one, what to do when it fails, what that means for staff, and a narrower alternative.

Short answerTo link WhatsApp to another phone, open WhatsApp on the second phone, choose to link it to an existing account, and scan the QR code with your main phone under Settings, Linked devices, Link a device. WhatsApp Web and the desktop app link the same way, up to 4 devices. To see linked devices on WhatsApp, open that same Linked devices screen: it lists every connected device and when it was last active. A linked device shows every chat, number and the recent history, so for a coworker InBetween can instead forward only new customer messages, without numbers, with replies going back from your business number.

How to link WhatsApp to another phone

  1. Install WhatsApp on the second phone and open it. Do not register your number on it: that would move the account and log out the first phone.
  2. On the screen that asks for your phone number, look for the option to link to an existing account. On Android it is in the menu behind the three dots; the exact wording differs between versions. The second phone now shows a QR code.
  3. On your main phone open WhatsApp. On Android tap the three dots, then Linked devices. On iPhone go to Settings, then Linked devices.
  4. Tap Link a device, unlock your phone if asked, and scan the QR code on the second phone.
  5. Wait until the chats have loaded. The second phone now appears under Linked devices and works with the same number.

How to link a device: WhatsApp Web or the desktop app

  1. On the computer open web.whatsapp.com in a browser, or the WhatsApp desktop app. It shows a QR code.
  2. On your main phone go to Linked devices and tap Link a device.
  3. Scan the code. Instead of a QR code, some screens offer to link with a phone number: you then type an 8-character code on your phone.

Your main phone does not need to stay online for a linked device to work, but if you do not use WhatsApp on the main phone for about 14 days, linked devices are logged out. To remove one, open Linked devices, tap the device and choose Log out.

How to see linked devices on WhatsApp

  1. Open WhatsApp on your main phone.
  2. On Android tap the three dots at the top right, then Linked devices. On iPhone tap Settings, then Linked devices.
  3. The list shows every linked device with its browser or device type and when it was last active. A device that is open right now shows as active.
  4. Tap a device you do not recognise and choose Log out. It is disconnected straight away.

There is no full history of linked devices: WhatsApp only shows the devices that are linked now, with their last activity. A device you logged out disappears from the list. If you see one you do not know, log it out and turn on two-step verification under Settings, Account. A tablet, such as an Android tablet or an iPad, is linked the same way as a second phone and counts as one of the 4 devices.

What a coworker sees with WhatsApp Web or a linked device

Linked devices let you use your WhatsApp account on up to 4 extra devices next to your phone: WhatsApp Web in a browser, the desktop app or a second phone. It is free and takes a minute. But a linked device is a full copy of your account. There is no setting to hide part of it.

Why this is a privacy question

A business number holds more than customer questions: conversations with your accountant and suppliers, family who have that number anyway, and the phone numbers of every customer. A coworker with a linked device can read, forward and screenshot all of it. When they leave, you have to remember to unlink the device.

When a linked device is fine

For a small office where everyone may see everything, linked devices are free and simple. Use InBetween when the person answering should only see the customer questions meant for them.

Forward customer messages automatically. Replies go back from your number.

Will my coworker see my old conversations with InBetween?

No. Only new customer messages that arrive after you connect are forwarded.

How do I check which devices are connected to my WhatsApp?

Open Linked devices on your main phone (three dots on Android, Settings on iPhone). Every connected device is listed with when it was last active. Tap one and choose Log out to remove it.
