Is there any web services or dead link finder software that can bypass the login page and find dead links?

I am a manual tester. I find out all the dead links in a web application, manually by clicking on each link in the web application. Currently, the web application in which I am working contain login page and dead link finder web application services present on the Internet cannot bypass the login page. So is there any alternative solution for this problem?

I know the method of passing credentials through the URL. And it is not allowed/ I cannot manipulate the code. Coding work is done by another development team.

I expect a solution like any web service/web site that accept the credentials separately and by using that it passes through a login page and find dead links/broken link. Rest your solution that can solve my problem are most welcome.
