@oldTimer , @padmavathi : I will explain you why the non-password version do not require password or how to use the non-password version. Before opening this software, you have to open Internet explorer and go to dataone admin site and login using your username and password. Then you have to navigate to the first log page of the month for which usage is to be checked. Leaving that IE window as it is, now you open the tool I have created, select "non password" tab and click "Check Bandwidth usage", So my tool is just retrieving data from the open Internet explorer, by navigating through all pages. Non-password version will work only for Internet Explorer.
