WhatsApp is one of the most popular messaging apps in the world, with over 2 billion users. WhatsApp started out as a mobile app, but they eventually created a web version that mirrors all the same functionality as the mobile app. This allows you to use WhatsApp on your computer browser. However, to connect your WhatsApp account to the web, you need to scan a QR code using your mobile device to link the two.
What is a QR code?
QR code stands for “quick response” code. It is a type of barcode that can be scanned by a camera, such as the one on your smartphone. QR codes store data like website URLs, text, phone numbers, etc. When you scan a QR code with your phone’s camera, it will take you directly to that linked data. For WhatsApp web, the QR code contains your account info to pair your mobile app with the desktop site.
How to get the QR code
Getting the QR code to connect your WhatsApp to WhatsApp web is easy. Just follow these steps:
- Open WhatsApp on your smartphone
- Tap the More Options icon (3 dots in top right)
- Select WhatsApp Web
- Point your phone’s camera at the QR code area on the WhatsApp web screen
- Your phone will scan the code automatically and you’ll see a confirmation on both devices that they are now linked
That’s all there is to it! The QR code is generated automatically when you try to connect to the desktop site. As long as your phone is on the WhatsApp Web scan screen, the code will be visible on your computer for you to scan.
How does the QR code work?
The QR code for WhatsApp web contains encrypted information that links your account on your phone to the desktop browser session. It acts as the “handshake” between the two platforms. Here’s a breakdown of what’s happening behind the scenes:
- When you go to web.whatsapp.com, the site generates a unique QR code image
- This image is tied to the specific browser session you initiated
- Your phone scans the QR code, decrypting data like an ID, timestamp, verification keys
- Your phone sends this info to WhatsApp’s server to verify the session is valid
- The server pings your browser session to complete the link
- An encrypted connection is now established between phone and browser
This all happens in just a few seconds! The QR code allows WhatsApp to verify your identity across multiple devices securely. Your chats and data stay safe since that unique code is only valid for that browsing session.
