When you sign in to WhatsApp Web, it means that your phone is connected to the internet and the WhatsApp app is open on your phone. This allows you to access your WhatsApp account on your computer and view your messages, contacts, and other data.
You can sign in to WhatsApp Web by scanning a QR code on the WhatsApp Web page using your phone's camera. This will link your phone to the computer and allow you to access your WhatsApp account.
It's worth noting that you can also use WhatsApp Web without signing in, but this will only allow you to view your messages and contacts, and you won't be able to send or receive messages.
If you're experiencing issues with linking your WhatsApp account to WhatsApp Desktop, you can try checking the WhatsApp support page for troubleshooting tips and solutions.
