How To Check if Someone Else is Using your WhatsApp Account

WhatsApp’s privacy and security is fairly good. It allows only one device at a time, users can verify their account with their mobile phone, and there is an option to enable two-factor authentication. However, this doesn’t mean that nobody will try to hack into someone else’s WhatsApp account. The online world isn’t totally safe as we all know.

So, we touch on the question, “How do I know if someone else is using my WhatsApp account?”

WhatsApp is continually gaining popularity all over the world with more than 2 billion users. With WhatsApp, you can make video calls, exchange messages, share files, do video calls, and create group chats – all for free!

The app does what it can to remain as secure as possible but there is no such thing as complete security when something is connected to the internet. You have some responsibility in keeping your WhatsApp account secure; a simple mistake can leave your account wide open to abuse.

The only attack vector that makes any sense while you still have your phone is WhatsApp Web. This has been covered extensively online already but is worth mentioning here. When you open WhatsApp on your phone, you can open a browser version to complement the app. If you don’t sign out or close the session, someone with access to that computer can take over. It’s a limited option but the only one I know of.

Using the web version of WhatsApp makes it a lot easier to type, as you can do it on a keyboard rather than tapping on your phone screen.

  1. Open a WhatsApp Web session by selecting the three dot menu icon in the main WhatsApp window.
  2. Select WhatsApp Web. This opens your camera.
  3. You will be directed to scan a QR code which you can get by opening WhatsApp Web in your browser.
  4. Open WhatsApp Web in your browser.
  5. Scan the QR code in your browser window with your phone camera.

Your WhatsApp window on your phone should be reflected in the browser, allowing you to chat and interact as usual.

Check if someone is using your WhatsApp

WhatsApp Web is the only way into your account that we know of with the exception of malware. WhatsApp authenticates using your phone number and is only accessible through one device at a time. That means as long as you have your phone in your possession and shut down your WhatsApp Web session, you’re about as secure as you can be online.

Symptoms of someone using your WhatsApp will include the obvious like messages appearing that you didn’t send, more listings in the Chats tab than should be there or accepted friend requests you didn’t make. Most hackers with any sense will delete all these but if you are quick enough to see some actions you didn’t make, that’s a sign.

If you use WhatsApp Web already, you may know that if you select it from the three dot settings menu, you can see what the last session was or if there are any open sessions. This is a sure fire way to find out if anyone is using your account.

  1. Open WhatsApp and select the three dot menu icon from the main window.
  2. Select WhatsApp Web.

If the camera opens, there is no active WhatsApp Web session ongoing. If you see a window that lists a logged in computer, there is an active session ongoing. Select ‘Log out from all computers’ underneath and enable two-factor authentication right away.

Enable two-factor authentication in WhatsApp

If someone has been using your WhatsApp account, you need to lock it down. If you’re lucky, it’s a sibling or partner spying on what you’re doing. If you’re not so lucky it could be a hacker stealing your contacts and data and wreaking havoc with your social life. Either way, you need to lock it down by turning on two-factor authentication.

WhatsApp doesn’t use passwords. Instead, you need to enable two-factor authentication. That way, anyone that tries to log in will need to enter a  verification code to do it.

  1. Open WhatsApp and select the three dot menu icon from the main window.
  2. Select Settings and Account.
  3. Select Two-step verification.
  4. Enable it and set your PIN code.

Once set, every time you open WhatsApp you will need to enter that PIN code to authenticate. Make sure the PIN isn’t something obvious and you have secured your WhatsApp account even further.

WhatsApp is a very secure app but is only as secure as you keep it. Using two-factor authentication is as secure as things get right now and is a viable way to lock down your account if someone has been accessing it.
