Account manager - custom account with own credentials

Hello, android-developers.
I have been reading about the account manager several days now, and also tried some implementations.
But as it seems, the account manager always takes "username" and "password".

But what, if I would like to create an account, which has more credentials ?
Let me say, a service -address(URL and portnumber ) , username, password, and 4 other values.

Is this easily possible ?

Hello again.
I managed it and it is very sad, that no one in here either knew, how to do this or did not respond.
Whatever. If anybody would like to know, how I did that, just reply.
