WebView is a software component that allows mobile or desktop applications to display web content directly within the app, without launching an external browser. It acts like a mini web browser embedded inside the app, enabling users to view websites, forms, or other online resources seamlessly. WebView is commonly used to integrate web-based features, such as help pages or login screens, into native applications. However, if not properly secured, WebView can introduce security risks, such as exposing the app to malicious web content or vulnerabilities.
