I need to test the accessibility of an online email app and another portion of a website that is only accessed after one logins. How can one test using something like www.achecker.ca if the content needs a username/password? Definitely need to do some CSS and HTML validation, but again cant really just paste the URL into the form since it wouldn't have proper credentials.
I hope this makes sense and any help you could offer would be greatly appreciated. Regards -PJ
