What if the website require to type in a Username and Password?

as shown in

btw the Username is a domain account like foo\bar

Solution

I'm guessing, we're talking about HTTP Basic authentication? If so, you can use something like

START http://username:[email protected]

Just tested, this does not work on newer versions of Internet Explorer. It works on Firefox and most likely on other browsers. Internet Explorer can save the password though, you'll have to use the dialogue on the page once.
