WhatsApp is he instant messaging service most popular in the world, and therefore the favorite of people to communicate with their friends, family or colleagues.
On the other hand, digital security is an issue of vital importance, because today practically all of the information of the users is found in the cloud (and it’s shared online), and that’s why criminals have come to ‘work’ in this realm. Thus, TechMarkup recommends the following keys to prevent someone from hacking a reader’s WhatsApp.
There is only 2 ways someone can get access to the app. Because WhatsApp can only be active on one mobile device at the same time, it is impossible for someone to be using the number of one user from another smartphone.
Nevertheless, yes there can be an indefinite number of sessions whatsapp web open, so it is better to be careful where they are open.
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 the conversations in some way. A) Yes, if you were talking to someone and you realize that messages are missing or that the person received messages that you did not send, someone is likely to have access. The same goes for deleted and archived conversations or new conversations that one did not make.
Another one is view the web devices to which WhatsApp is linked. The application keeps track of all the computers it has connected to via the web. If you review the list, you can see which are the active sessions, and when and from where they were initiated. If none are recognized, it is known that someone has access to the account.
This is how you can protect a WhatsApp account
The first thing to do is check if someone has access to WhatsApp via web. To do it:
In iOS: anger Settings > Linked Devices. There will appear the sessions that have been activated, where, when and in what operating system.
You have to check that they are all recognized. To close a specific one you simply have to swipe leftor if you want to close all of them, just click on the standalone button.
In Android: click on the menu 3 points in the upper right corner, and then on WhatsApp Web. The sessions that have been activated, where, when and on what operating system will appear.
As in iOS, you can close a specific session (by long clicking on it) or close all permanently with the corresponding button.
Once the user has made sure to remove web access to any possible spy, it remains to activate the verification in 2 steps. This security measure will ask the user to choose a 6-digit PIN, and they will have to enter it if they ever want to change their device and migrate their WhatsApp account.
In addition, WhatsApp asks that the user confirm the password from time to time, so the measure doubles as a blocking method that won’t let someone else access your messages even if they were to access the device remotely.
For enable 2-step verification, anger Settings/Settings > Account > 2-Step Verification > Activate.
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 to having to explain to contacts why one started sending strange messages.
