For several years, using the same WhatsApp account on multiple devices at the same time has been one of the most popular requests from messaging app users, as a large number of people want to use WhatsApp on multiple mobile devices. However, if you do not want a stranger to access your WhatsApp account, it is possible to prevent it.
Here’s how to find out who’s using your WhatsApp account without your knowledge and block any future access attempts.
Using the multi-device mode is the most recommended way to have the same WhatsApp account on two mobiles, since it is the official method approved by WhatsApp. Using this mode is very simple. You only need to have your WhatsApp account already configured on a mobile, and a secondary mobile where you will associate the account. Furthermore, you can also link your account to an Android tablet if you want.
With Play Store
- Enter the Play Store (from your secondary smartphone) and download the latest beta version of WhatsApp.
- Open the app and when it asks you to enter your phone number, you have to tap on the three dots icon.
- You will see some options and you will need to choose ‘Pair device’.
- Your second mobile phone will show a QR code, which you have to scan with your main phone, just as if you were opening WhatsApp Web.
- After a few minutes, your WhatsApp chats will appear on the secondary device.
As you can see, this is a very simple and quick process to do. In a few minutes you will have your WhatsApp account available to be used on any of the two devices simultaneously.
With WhatsApp Web

Another effective way to use WhatsApp from two devices simultaneously is to use WhatsApp Web, the version of the messaging app for tablets and computers.
If you use this trick, you need to open your computer and follow these steps:
- Open the secondary mobile browser and, from the menu, activate the “desktop mode” or “computer version”.
- Access the WhatsApp website. Sign in with the account associated with the primary device.
- And that’s it, you have WhatsApp on two phones at the same time.
This solution is not the most practical of all. After all, WhatsApp Web is designed to be used through a computer and not from a mobile phone.

Knowing that a third party is spying on your WhatsApp account can be very annoying, even worrying because there is a possibility that it could be opened by another remote device. As you may have noticed, opening your WhatsApp account on another smartphone is very simple. Fortunately, there is a way to tell if an external device is using it.
- Enter WhatsApp from your main phone.
- Tap on the three dots icon and select “Connected Devices.”
- The app will display the computers you are logged into.
- If you find an unknown device, proceed to disconnect it.
Finally, sharing your WhatsApp authentication data with third-party applications is strongly discouraged, especially if these were not created by official sources associated with Facebook and WhatsApp.
