Secret Scanner is a Chrome extension designed to enhance web security by scanning web pages for sensitive information such as API keys and passwords. This free add-on allows users to easily identify potential security risks embedded in JavaScript files loaded by the websites they visit. Users can initiate scans directly from the toolbar, making it a convenient tool for developers and security-conscious individuals alike.

To use Secret Scanner, simply navigate to the desired webpage, click the extension icon, and select 'Reload & Scan Page' to begin the analysis. Detected secrets will be displayed promptly in a popup notification. However, it is important to note that the tool operates within certain limitations, including the potential for false positives and the inability to catch dynamically constructed secrets.
