can't login to phpMyAdmin-help!

I don't know how to login to phpMyAdmin. I didn't get any username and password speciffically for phpMyAdmin from my host. Do I have to create username and password first somewhere ? How?
Can anybody help me ?

You must create the database and set the username passwords through DirectAdmin first.

Thank You, but that's exactelly what I do and when I try to login into phpMyAdmin using username and password I created for database it does not function. The login script denies access as if it was wrong username or password. After a coupple of login attempts I come to phpMyAdmins homepage but I have no privilegies att all eaven if I enable all privilegies in direct admin, and I can do nothing there. Is it possible that my host have to change something in phpMyAdmin settings or direct admin settings ? Maybe he configured something wrong ?

Yes it's possilbe. If you do not own the server then I suggest contacting your hosting provider to resolve the situation
