wget can send a web username/password in the URL in the normal way. It 
shouldn't need to do anything with cookies.

      wget http://username:password at site.com/dir/file

So start at the top of your site with whatever index page it uses, and 
then use the tools of your choice to extract all the link filenames as a 
loop and use wget to get them.

      wget -O - http://username:password at site.com/dir |\
          tidy5 -i -n -c -asxml - |\
          lxprintf -e a "%s\n" . | while read file; do \
              wget http://username:password at site.com/dir/$file; \

Depending on how the names are exposed you may need to do more massaging 
to get filenames in a format you can append to a URI.

tidy5 is the HTML5 version of HTML Tidy, from W3C
lxprintf is part of the LTxml2 toolkit from Edinburgh
