3 methods using file verification: 

Manual file upload 

• Download the verification file: Use the provided “Download file” button to save the file to your local system. 
• Upload the file to your website’s root directory: Place the file at the path shown on the screen (e.g., https://yourdomain.com/_.txt).  
• Verify accessibility: Beagle Security will check if the file is accessible from the given URL. You can test this by visiting the link directly in your browser. 
• Click “Verify domain”: Once the file is placed correctly, click the Verify domain button to complete the process. 

Once your domain is verified, you’ll be directed to the Beagle Security dashboard, where you can configure your test settings and start your first application security test.
