If you believe someone has scanned your QR code and has access to your account via WhatsApp Web, use the instructions above to log out of all your active web sessions in WhatsApp on your mobile phone.
Note: If you’re unable to scan the QR code, ensure that the main camera on your phone is functioning properly. If the camera isn’t able to auto-focus, blurry or is broken, you may not be able to scan the barcode. Currently, there’s no other way of logging into WhatsApp on your desktop.
