Creating PDF from password protected website

Hi All,

I am trying to create pdf of all the webpages of a course from a website which asks for login credentials, but i am not able to. Whenever i try to create pdf using acrobat pro dc, it shows first page as login page and if i enter credentials there, i am getting error and downloading stops. I am new to acrobat dc reader. Please help me with this.

Thanks and Regards,

Ranjeet Singh
