Trying to scan a QR code to log in to WhatsApp Web but it’s not working? There could be several reasons why the QR code is not scanning properly on the WhatsApp Web login screen.
Common Reasons the QR Code Doesn’t Scan
Here are some of the most common reasons why the QR code won’t scan on WhatsApp Web:
- The camera on your computer is not working or properly configured
- The QR code image is too small or blurry
- There is not enough contrast between the QR code and background
- There is a glare or reflection on your computer screen
- Your computer does not have permission to access the camera
- You’re using the wrong QR code
- The QR code has expired
- Your internet connection is slow or unstable
- The WhatsApp app on your phone is not connected to the internet
Let’s explore each of these issues in more detail.
Camera Not Working or Configured Properly
In order to scan a QR code, your computer needs a working webcam that WhatsApp Web can access. If you don’t have a built-in webcam, you’ll need to connect an external USB webcam.
Make sure your webcam drivers are up to date and check that the camera works properly in other apps like Skype or Zoom. If the camera still doesn’t work just for WhatsApp Web, you may need to check your browser permissions or reinstall WhatsApp Web.
QR Code Image is Too Small or Blurry
For the QR code to scan properly, the image needs to be large and clear enough for the webcam to read it. Here are some tips to fix a small or blurry QR code:
- Zoom in on the QR code as much as possible so it takes up most of your screen
- Try scanning from a closer distance, about 6 inches from the webcam
- Check that your computer screen is free of dirt and smudges over the QR code
- Adjust your monitor settings for sharper image quality
- Scan the QR code in a well-lit room and eliminate glare from overhead lighting
Not Enough Contrast Between QR Code and Background
The QR code should clearly stand out from the background for the best scan results. Try adjusting the background or QR code colors to increase the contrast.
For example, a black QR code on a white background provides the most contrast. If the background is too colorful or dark, try changing it to a more neutral color.
You can also try increasing the brightness/contrast of your computer screen temporarily to make the QR code stand out more.
Glare or Reflection on Your Computer Screen
Glare or reflections from indoor lighting or sunlight can interfere with the QR code scan. Try these tips to reduce glare:
- Close blinds/curtains to block sunlight if needed
- Move your computer screen to face away from windows or overhead lights
- Adjust the angle of your screen to minimize glare
- Use a glare reduction filter or reposition light sources
- Increase your screen brightness to compensate for glare
Computer Lacks Permission to Access Camera
Most browsers will prompt you the first time WhatsApp Web tries to access your camera, so you can allow or deny permission. If you accidentally denied access, here’s how to update your permissions:
- Chrome: Click the lock icon > Site Settings > Camera > Allow
- Firefox: Click the lock icon > Site Permissions > Camera: Ask to Allow
- Safari: Preferences > Websites > Camera > Always Allow
- Edge: Settings & Privacy > Site Permissions > Camera > Allow
Using the Wrong QR Code
Each QR code on WhatsApp Web is generated uniquely for your account when you click “Log in with QR code”. Make sure you are scanning the latest QR code instead of one previously generated. The QR code will refresh automatically every minute or so.
QR Code Has Expired
The WhatsApp Web QR code expires after a certain amount of time if not scanned. This helps keep your account secure. If your QR code is expired:
- Refresh the WhatsApp Web page in your browser
- On your phone, close and reopen WhatsApp
- On WhatsApp Web, click the three dots menu > Log Out
- Generate a new QR code and try scanning again
Slow or Unstable Internet Connection
Scanning the WhatsApp Web QR code requires your computer and phone to have a reasonably fast, low-latency internet connection. Problems like lag, high ping, congestion, or limited bandwidth can prevent the QR scan from completing properly.
Try switching to a more reliable WiFi network or moving your computer and phone closer to the router. Turn off or disconnect other devices using your home internet to free up bandwidth. If issues persist, contact your internet service provider.
WhatsApp App Offline
In order for WhatsApp Web to sync properly, the WhatsApp app must be connected to the internet on your paired mobile device. If your phone loses connectivity due to bad signal, Airplane Mode, or Do Not Disturb modes, the QR code won’t scan.
Make sure your phone has cellular data or WiFi enabled and manually open the WhatsApp app to sync if needed. The app must remain open in the background while using WhatsApp Web.
How to Fix QR Code Not Scanning on WhatsApp Web
Based on the possible reasons above, here are the key steps to troubleshoot and fix WhatsApp Web QR code not scanning issues:
- Check computer camera permissions and enable access for WhatsApp Web
- Ensure QR code is large, crisp, and has good contrast from background
- Minimize glare, reflections, and smudges on computer screen over QR code
- Use a stable, high-speed internet connection on both devices
- Confirm WhatsApp app is connected to internet and open in background
- Generate a fresh QR code if needed and scan from close distance
Following these tips should allow you to successfully scan the QR code and login to WhatsApp Web in most cases. Let’s look at some additional troubleshooting methods for tricky situations.
