Adding secured RSS to the Notes 8.0.2 sidebar

I have tried to add RSS to my Notes 8.0.2 sidebar and I have got error 401 (Unauthorized) :(I think I have got such error because this RSS requires login and password.

How can I set login and password for RSS???

You need to create an account for the HTTP server which is hosting the feed you want to subscribe to.

Note: In 8.5.x you will be prompted for credentials when attempting to authenticate to the feed server using basic authentication.
