How to know if someone has access to your WhatsApp and how to protect yourself

WhatsApp is the most popular instant messaging service in the world, and for this reason people’s favorite to communicate with their friends, family or co-workers. On the other hand, digital security is an issue of vital importance, since today practically all of our information is found (and we share it online), and that is why criminals have started to ‘work’ in this area. Follow the recommendations below to prevent someone from hacking your WhatsApp.

There are only 2 ways someone can get access to your app. Because WhatsApp can only be active on one mobile device at a time, it is impossible for someone to be using your number from another cell phone. However, there can be an indefinite number of WhatsApp Web sessions open, so you have to be careful where you open them.

How to know if someone has access to my WhatsApp?

One way to tell if someone can break into your WhatsApp is if the person interacts with your conversations in some way. So, if you were talking to someone and you notice that messages are missing or that the person received messages that you did not send, it is likely that someone has access. The same goes for deleted and archived conversations or new conversations that you didn’t start.

Another one is to see the Web devices to which your WhatsApp is linked. The application keeps track of all the computers it has connected to via the web. If you check the list, you can see which sessions are active, and when and from where they were started. If you don’t recognize any, you know someone has access to your account.

How do I protect my WhatsApp?

The first thing you should do is check if someone has access to your WhatsApp through the web. To do it:

On iOS: Go to Settings> WhatsApp Web/Desktop. There you will see the sessions that have been activated, where, when and in what operating system.

Check that you recognize all of them. To close a specific one just swipe left, or if you want to close all of them, just click the separate button.

On android: Click on the 3 dots menu in the upper right corner, and then on WhatsApp Web. You will see the sessions that have been activated, where, when and on what operating system.

As in iOS, you can close a specific session (by long clicking on it) or close all permanently with the corresponding button.

Once you have made sure to remove web access from any possible criminal, it remains to activate the verification in 2 steps. This security measure will ask you to choose a 6-digit PIN, and you will have to enter it if you ever want to change devices and migrate your WhatsApp account. In this way, if someone wants to take your account ‘the wrong way’ trying to log in from another cell phone, they will not be able to do so because they do not know your password. In addition, WhatsApp asks you to confirm the password from time to time, so the measure doubles as a blocking method that will not allow someone else to access your messages even if they were to access your device remotely.

To enable 2-Step Verification go to Settings/Settings>Account>2-Step Verification.

It is not very common for a person to lose access to their WhatsApp account. However, this does not mean that it cannot happen, so taking preventive measures will always be better than having to explain to your contacts why you started sending them strange messages.
