Based on the search results, "zap web" is likely a misspelling of "WhatsApp Web," which is a browser-based PC client of the WhatsApp messenger. WhatsApp Web allows users to send and receive WhatsApp messages online on their desktop PC or tablet. It is not a separate account, but rather a browser version of the WhatsApp Messenger. Users can access WhatsApp Web by visiting the web.whatsapp.com website and scanning a QR code with their phone. There are also third-party apps available, such as Web Messenger for WhatsApp Web, that allow users to access WhatsApp Web and other messaging applications from their desktop.
