The article quite well describes some of the valuable features of a good login UI.

The login page is (often) the first place a user encounter your site. If that page creates a sense of repulsion in the user or forces him to struggle, the user is probably left with a feeling that your site is against him. That's not something you want.

Its not difficult nor time-consuming to implement a proper login UI. However, surprisingly many sites don't pay enough attention to it.
