This review is for a previous version of the add-on (2.3.1). 

The reader does not manage the authentication to the website.
Only basic authentication could be done by setting the user name and password directly in the feed URL.

You can login in your forum and choose "remember me". As you are connected to the website the reader will be able to request the feed.
