Can You Use the Same WhatsApp Account on Two Phones?

Yes, you can use the same WhatsApp account on two phones. In 2021, WhatsApp introduced support for Linked devices. It allowed users to use the app across many devices. However, the downside was that you could only connect one smartphone to a single WhatsApp.

That changed in April 2023 when WhatsApp launched Companion mode. The mode allows users to use a single WhatsApp account on all their devices. Chats, contacts, and groups are synced across the devices.

You can link up to four phones to the same WhatsApp account. The setup process is the same as the existing Linked device feature. However, the Companion mode is different as it's designed specifically for smartphones.

Be it the iPhone or Android that you opt to add, each linked phone connects to WhatsApp independently. That ensures that your personal data and calls are end-to-end encrypted. Also, your primary device must not stay inactive for an extended period. WhatsApp will automatically log you out of all companion devices if it does.

That said, discover how to use WhatsApp on two phones with the same number below.

How to Use WhatsApp in Two Devices via the Companion Mode

Knowing how to use one WhatsApp account on two phones is important. You can use the app on one phone and continue from where you left off when you switch to your other phone. Learning this essential skill also makes sharing an account with a family member easy.

Whatever your intention is to want to use WhatsApp on two phones, the Companion mode has got you covered. You only need to ensure your primary phone is running the most recent version of WhatsApp. After that, follow the steps below to learn how to use one WhatsApp account in two phones.

  1. Download the latest WhatsApp version on your other phone.
  2. Open the app and follow the installation steps on the screen. First, choose your language and proceed. On the next screen, tap Agree and continue. That will take you to the login screen.

Your WhatsApp will now appear on both phones. And you can use the account on both devices without any problem. As mentioned, both will work independently.

Even when your primary device is locked, you can still use WhatsApp on the secondary phone. Just ensure the primary device isn't disconnected for an extended period. Otherwise, WhatsApp will log you out on the secondary phone.

WhatsApp Features Found on Secondary Phone

The companion device carries over most of the original WhatsApp features from the primary phone. These include the biometric lock feature. The feature allows you to lock access to your WhatsApp chats.

Additionally, disappearing messages in chats are carried over to the secondary device. That enhances privacy. You can even set an online status, custom last seen, profile photo, and About visibility. Just like you would on your primary device.

If you want to read receipts, the WhatsApp companion mode offers that, too. Generally, WhatsApp works perfectly on secondary devices. There are no delays in sending or receiving chats. WhatsApp messages are instantly synced between the two phones. If you delete a chat on the primary device, it also gets deleted on the companion device. And vice-versa.

Logging Out of WhatsApp on the Secondary Phone

You can decide to no longer use your WhatsApp account on two devices. That could be due to privacy or other reasons. In that case, you can easily log out of the secondary phone. Follow the steps below:

  1. Open WhatsApp on your secondary phone and go to Settings.
    open whatsapp on your secondary phone and go to settings
  2. In Settings, choose Account and tap Log out.
    tap account and then the log out button to log your secondary phone from whatsapp
  3. Tap Log out again to confirm your choice. You'll have successfully logged out of WhatsApp on your secondary device.
