broken link checker on password protected site

Hi Kentico team, we're running our intranet on v10.0.1 and have recently undertaken a redevelopment. There are a huge number of broken links but there doesn't seem to be a way of doing a site-wide check (and can't use an external link check as the site is password protected. I did search DevNet and found this: https://devnet.kentico.com/questions/site-wide-link-checker Just wondering if there was a way to site-wide link check without external software or a plugin? If not then what would be the preferred option for a mac OS? thanks so much! Caroline
