Have you ever wondered how whatsapp web really works? It seems like magic when you capture the QR code with your mobile phone and you can start chatting with your contacts, but the reality is that everything is quite simple to understand, as you will see below.

Perhaps one of the most surprising details when using WhatsApp Web for the first time on your PC is that by capturing a simple QR code, your computer screen magically changes and the WhatsApp Web home screen opens with your conversations.



Another aspect that can create more confusion is the fact that you must have your cellphone near your computer and with an internet connection so that WhatsApp Web can work smoothly, so that you can see all your synced conversations on both sites.

WhatsApp Web is not an independent service

We can say that WhatsApp Web is not a standalone web client, but rather a method to access WhatsApp via mobile. And is that what this possibility really does is connect to your mobile phone to download all the information you see on your PC and make the connection via said device.

This is why you should have your cell phone nearby, because WhatsApp Web really does have an "open connection" with the WhatsApp app on your smartphone permanently, so you can see messages, images and other messages in real time and synchronized with the terminal and on the computer.

You may have noticed that from the moment you move your mobile or run out of Internet, WhatsApp Web informs you that something is wrong and that it cannot establish the connection, which is quickly resolved only by placing the smartphone next to the PC.



Although it may seem a bit annoying, it has its advantage and it is related to security. It may happen that by mistake you are on a PC with a WhatsApp web session opened and at some time you go out with your mobile, another person could access your messages, but could not receive new ones or see the ones you send, but in this case it is always better to log out of any WhatsApp web location.

What the QR code contains

Although the information contained in the QR code offered by WhatsApp Web to make the connection between the PC and the mobile, the logical thing is that it had all the information of your WhatsApp profile and the parameters necessary to make the connection between the devices.

If you try to scan the QR code with your camera, you won't see more than one series of numbers, letters and symbols that say nothing, they don't lead to any url or anything because they don't lead anywhere from the browser. In any case, your QR code is unique and you shouldn't show it to anyone.

This QR code is not always the same, it always varies, you may also realize that when you go and capture what you see on your PC with your mobile to make the connection, it changes every few seconds, so what is now will not be the same which will be available 10 seconds later.


How to use WhatsApp Web

Once the functioning of WhatsApp Web has been explained, these would be the steps you need to follow to use the service:

  1. Open the WhatsApp website.

Web: WhatsApp Web


  1. Take your mobile, open WhatsApp and go to Settings / WhatsApp Web.


  1. Click on the device link and now capture the QR code that appears on the web that you opened in the first step with your mobile phone's camera, in a few seconds a new session will open in your browser to chat via Web WhatsApp, remember to have your mobile close forever.
