How to Know if my WhatsApp Account is Being used on Another Phone?

Know if your WhatsApp account is being used by others in another device and also learn how to protect your WhatsApp from hacking.

Though you cannot use same WhatsApp number in two devices at the same instance. But anyone can spy on you with a feature known as WhatsApp Web. WhatsApp is a popular internet messaging App and looking at the nature of the App it is one of the most private of the software present on the Android. If unknowingly a rouge gets access to your WhatsApp it may create great repercussions.

I have found several ways to know if someone is spying on WhatsApp. Today in this post I will tell you how you can find which other phone or PC is accessing your WhatsApp. Also, I will explain how to keep yourself safe from breach or hacking.

How to Know if Your WhatsApp is Being used on other Device?

Many times people are very much very interested in your life and to sneak into your living, the most powerful tool they can access is your WhatsApp. All they need is few seconds of your unlocked phone and WhatsApp Web Barcode. Boom!!

He/She can now see an exact duplicate of your WhatsApp account with all the chat and media. The WhatsApp on your cell phone will work normally. However, everything you send or receive will be reflected on the spying device.

How to Know if they Spy via Whatsapp Web?

In case if you missed, I want to let you know that the first evidence will appear on the cell phone itself in the form of a notification.

You can check any account usage by doing the following.

  • Open WhatsApp.
  • Click on the menu option indicated with 3 vertical dots at top right corner.
  • Here click on WhatsApp Web option and you can check for any device or App which has access to your WhatsApp.

If one or several computers with open session appears, then your WhatsApp is accessible to those on another device. Your account is “intervened” and they are spying on you.

What to do if WhatsApp is Open on Another Device?

To prevent the WhatsApp from being hacked you can log out of all the sessions that are open and the person will lose access to your account immediately.

To avoid these things happens again, the most effective solution is to configure the WhatsApp with App Lock. In this way, even if someone gets your phone, they can not access the WhatsApp application and connect it to a PC or other App via WhatsApp Web.

Know if WhatsApp is Open on Another Device (2nd Way)

Another way in which persons can spy WhatsApp is activating the account in another device. Basically, they register your WhatsApp number in another mobile and during their configuration, they recover all your chats or conversations saved in the application. Anyone can do this by taking your cell phone, to receive the verification code that WhatsApp sends.

If such a thing is done then on your phone, it will appear that “This phone could not be verified” because the number is registered on another device.

You can re-verify your number to regain the account access.

Protect Your WhatsApp Account from getting Activated on other Device

There is a much-sophisticated method to protect your WhatsApp from getting active on another phone. All you need to do is enable two-step verification.

To do so go to;

WhatsApp → Menu options at Top Right → Settings → Account → Enable 2 Step-verification.

When someone tries to activate your WhatsApp on another device, he will be asked for a security code that only you know. Without that code, it will be impossible for another person to register your WhatsApp on another computer.

Note & Conclusion: Although WhatsApp is end to end encrypted, to make sure check WhatsApp web in settings if there’s some device connected remove it or else there is no other way to hack into someone’s WhatsApp as of yet unless he or she has your phone with all the apps unlocked.

    Thank you for the effort, your above article is very useful. Unfortunately my account was hacked and I’m waiting for the 6 days to pass to regain my wahtsapp account as I do not recall the 2nd verification pin.
    Does this solve the problem and the hacker set up will be blocked?
    Is he also blocked in due time?
    Highly appreciate your response

    Hello… I have a follow up question to this because the same thing happened to me recently… Someone took the 6 digit code on the SIM and registered a new Whatsapp on another phone with my number and I couldn’t access my whatsapp… When I did the re-verification on my phone Whatsapp asked me for the 2 step verification PIN (which I know I never activated in the first place), and which means this hacker actually set up 2 step verification after he registered my number in another phone. I am now waiting for 6 days to pass as I don’t know the PIN obviously. The question is will that solve my problem and will I be able to reverify after the 6 days and more importantly in the meantime will the other person not be able to use my account in the meantime?

    Hey.. Someone registered a new Whatsapp on another phone with my number and I couldn’t access my whatsapp… When I did the re-verification on my phone Whatsapp asked me for the 2 step verification PIN (I did not activated), and the hacker actually set up 2 step verification after he registered my number in another phone. I am now waiting for 6 days to pass as I don’t know the PIN obviously. Plz answer me.. Will I be able to reverify after 6 days ?? And in the meantime will the other person be able to use my account? What is the solution for this?

  8. dongjun says:

    But the Desktop version does not request for 2 step verification as opposed to what you have mentioned –>>”””Without that code, it will be impossible for another person to register your WhatsApp on another computer.”””

    May i ask if its really requesting for code for web base access? I tried and it is not asking for the code. Then how can i assure my account is safe for web base and how will this loophole compromise my account?

    Hi everyone I hide my” last seen ” on WhatsApp and lately I noticed 1 contact would show the last seen but the rest of my contacts don’t, asked the user he says he doesn’t know what is happening, could he be doing something to track my last seen? How can I find out? I did all the 6digits and Email blocking, also the WhatsApp web nothing is showing. Hep

  15. Jaanu says:

    Hi, I think my whatsapp may be hacked. When I close the application I still appear to be “online” on my partners chat to me for up to a minute. Even when I turn my phone off!! How is this possible?

    • Nikhil says:

      If you can see any device on your WhatsApp Web Then probably your WhatsApp is compromised. But if no device is shown as logged in then it is just a technical glitch because the servers may not be able to detect the activity of your WhatsApp even though it is turned off. Don;t worry it is normal.

    thank you so much for your efforts

  17. Maggie says:

    My ex hacked my What’s Up. I have logged out of all devices on What’s up Web but from emails I get from him and threats I think he still reads my What’s up messages. If he registered my what’s up on his device will putting two step verification stop him from spying me? Am I safe now? It really is freaking me out.
