Server name and database ID

My site's host won't allow remote access to databases so baseportal seems the ideal solution for storing a list of user names and log in details, but I have the following query.

Using an application called easyGen, from a company called Symbiant, I have created a login page and a username page for the site, which needs to be exported to my database. When it comes to configuring the export details, there are the following fields to input:

Database - Only options given here are MySQL and Access, which do I choose?
Server - I presume this is asking for the name of the server carrying the database, what is the name of the baseportal.com server?
Username - my username at baseportal.com, I guess
Password - my password, I guess
database - I gues this is the name of the database I created, should I put the address as "http://baseportal.com/baseportal?htx=main&uid=mandrew", the route to my database? If not, what?

And I only want to enable myself and two other site owners to view and modify details, how do I go about doing that?

Thanks.
