Until July 2022, one of the big problems with using the WhatsApp on the computer was that the cell phone with the active account needed to be connected to the internet at all times for the synchronization to take place. But that is a thing of the past and nowadays it is possible to use the Web WhatsApp without smartphone after a single validation is done. And it all takes less than a minute.
See how to access the same messages on your cell phone, directly on your computer, without the need to keep the smartphone connected to the internet.
Process of connecting WhatsApp Web
Besides the official functionality website which can be accessed by all browsers, you can install free app of Web WhatsApp available for computers with Windows🇧🇷 The two options work in almost the same way: simulating the application to smartphones for you to receive and send messages in groups to friends and family. Let's go step by step.
1. Already with the application or page of Web WhatsApp open on your desktop computer or notebook, you will see a QR code that needs to be scanned by the cell phone camera you use in your day to day life.

2. On the home screen of the WhatsApp all with smartphones, click on the three-dot menu located in the upper left corner of the screen, and then on connected devices🇧🇷 Now select the option connect a device.

As a security process, it will be necessary to authenticate the new connection of your account with a new device, by reading a fingerprint, entering a PIN or another way to confirm that the owner of the account WhatsApp is actually requesting the connection.
3. When the security validation is completed, just scan the QR code that appears on the computer or notebook screen and wait for the synchronization to complete. It may take a while for all the messages to appear, so it's worth letting everything load for a while and then start receiving and sending messages to whoever you want.

After this single connection, in a second moment, you can already use the Web WhatsApp without the need for your cell phone or tablet to be connected to the internet. This is because the application (or browser tab) will be authenticated to your account.
Is there a way to use WhatsApp Web with the cell phone turned off?
Yes, but only after connecting to the computer through the smartphone🇧🇷 This is because the “new” version of Web WhatsApp left the main device's internet connection aside to receive and send messages.

However, it is important to remember that you must not connect your WhatsApp in public machines, such as libraries, colleges and other spaces frequented by more people. After the security validation is performed, the messages will continue to arrive (even if the cell phone is turned off or the computer is restarted). Pay attention to this.
How to enter WhatsApp Web with just the number?
As it requires reading a QR Code for message history and security validation to be performed, you cannot log in to Web WhatsApp with just your account number.
If you lost your smartphone or it has broken for some reason, one way to gain access to your account is through the use of Android emulators, but keep in mind that all message history will be lost and you will still need a device to receive the confirmation SMS of the account.
How many devices can I connect to my WhatsApp account?
According to an official statement from the WhatsApp, you can sync messages and send them to up to four devices in addition to your smartphone🇧🇷 All devices linked to your account can be viewed through the “Connected Devices” tab in the settings menu, and it is even possible to check the moment when they were last used.
Are messages synchronized between WhatsApp Web and mobile?
Yea! The desktop version of the messaging app is like an extension of the desktop version. smartphones and the messages sent by the computer can also be seen on the smartphone and vice versa.
End-to-end encryption is also valid for devices with larger screens and you don't have to worry about leaks of messages or files sent on your computer or notebook.
Telegram also allows connection between multiple devices
Although users of WhatsApp have access to the multi-device connection feature for use without the need for smartphone only in 2022, who uses Telegram can do this since 2018. We can even say that whoever uses the competitor of Meta owns a upgrade of this functionality, since the backup of messages is saved on the company's servers and can be downloaded right after the security validation with the smartphone.

According to the official website of Telegram, it is possible to connect to as many devices as the user wants, which allows greater freedom in everyday life. However, you also need to be careful when connecting your blue app account on computers used by more than one person. Once security validation via smartphone is performed, all messages will be synchronized (regardless of whether your cell phone is connected to the internet or not).
