At this point, open WhatsApp on your smartphone (or tablet) and select the tab Chat which is located at the top. Then press the button (...) located at the top right and choose the item Web WhatsApp from the menu that opens. On the next screen, if this is the first time you connect your WhatsApp to WhatsApp Web or WhatsApp for Windows / macOS, you will be shown a presentation screen to explain how the service works.
So press the button OK! I GOT IT and scan the QR code simply by framing it with the camera of your device. Make sure you frame the code by keeping the right distance from the PC with a steady hand: the code must be inside the light box and its edges must match the white indicators you see on the phone or tablet screen. Furthermore, in the event that an unlocking method via biometric recognition is set on your smartphone, this will also be required to access WhatsApp Web.
If it is not the first time you are using WhatsApp Web or WhatsApp for PC, you can start scanning a new QR code and then access WhatsApp Web and WhatsApp for computer from a new workstation by pressing the button (...), selecting the item Web WhatsApp from the menu that opens and pressing the button capacitor positive (+) lead located at the top right.

Think carefully before proceeding and scan the QR code!
Scan QR codes received on WhatsApp
Have you received a QR code within a conversation on WhatsApp and do not know how to find out its content? Don't worry, all you need is a free application that you can find on the Google Play Store: its name is QR Droid and it is extremely easy to use.
To install QR Droid on your smartphone (or tablet), open the Play Store (the icon with the colored ▶ ︎ symbol located on the Android home screen or on the screen where there are the icons of all the apps installed on the device), search QR Droid inside and proceed by tapping first on the application icon (the green robot in the QR code) and then on the button Install / Accetto.
When installation is complete, start QR Droid, skip the initial presentation screen and first press the icon with i 9 squares you see at the top right and then on the button More…, which you find in the screen that opens. At this point, choose the option Image decoding, indicates the application with which you want to select the image that contains the QR code (eg. Google Photos o Gallery) and proceed with selecting the image to decode.
Within a few moments, QR Droid should show you the content of the QR code present in the selected image. If in the list of images saved on your smartphone (or tablet) you cannot find the image with the QR code you received on WhatsApp, open the chat in which the code was sent to you and start downloading the image pressing the icon of arrow placed on its miniature. If you do not see any arrow on the thumbnail of the image, press directly on the latter, tap the button (...) collocato in alto a destra, selects the voice Share from the menu that opens and choose an application in which to save the file (eg ES File Manager or any other file manager for Android).

As I did in the chapter of the guide dedicated to Android, also in this case I remind you that by leaving the check mark on the option Stay connected you can save time by not scanning the WhatsApp Web / WhatsApp Desktop QR code again, but you can face potential privacy risks (access to services will remain open and therefore your chats will potentially remain at the mercy of anyone who touches to your PC).

Manage access to WhatsApp Web / Desktop
For the privacy issues I have told you about several times in this post, I highly recommend that you check the list of accesses to WhatsApp Web and WhatsApp Desktop: in this way you can close any access from a computer you no longer use and you will be able to detect any unauthorized access to your account (quite remote risk, but not entirely non-existent).
To check the list of accesses to WhatsApp Web and WhatsApp Desktop, start the WhatsApp application on your smartphone. At this point, if you are using a device Android, first presses the button (...) located at the top right and then on the item Web WhatsApp present in the menu that opens. If you use a iPhoneinstead, go to the card Settings (bottom right) and go up WhatsApp Web / Desktop.
At this point, consult the list of all open WhatsApp Web / WhatsApp Desktop sessions and, if you use a terminal Android, presses on the ones you want to close, then confirming with the button Disconnect. If you use a iPhone, instead, identify the WhatsApp Web / Desktop sessions you want to close, swipe them from right to left and press the button Disconnect that appears from the side.
If you want, you can also close all currently active WhatsApp Web and WhatsApp Desktop sessions. How? Simply pressing on the item Disconnect from all computers and confirming with the button Disconnect that appears on the screen. All computers that had access to your WhatsApp account will be disconnected and will then require the QR code to be scanned again.
