How to log in to WhatsApp Web without scanning a QR code
In some cases, scanning the QR code may not be a viable option. Fortunately, WhatsApp has implemented an alternative method for logging in without using your phone's camera.

- Receive and use the verification code: WhatsApp will send you an 8-character code that you must enter in the browser.
- Confirm on mobile: On your phone, open WhatsApp, go to “Linked Devices,” and select “Link to Phone Number.”
This method is especially useful when your phone's camera is damaged or when the QR code doesn't load correctly in your browser. For more details on WhatsApp security, you can consult this article on two-factor authentication.
