SEO Page Auditor can work with basic HTTP-authenticated environments, including many staging and password-protected test pages.
If a protected page fails to load:
- Verify that the URL is correct.
- Confirm that the credentials are valid.
- Make sure the environment is using basic HTTP authentication rather than a more complex login flow.
- Ask your IT or development team whether additional access restrictions are in place.
If the environment depends on custom authentication layers, captchas, or non-standard access logic, additional limitations may apply.
