Database user name: [first 10 characters of domain name] + [random 6-digit number]
example: if the domain name was "bob.the-mechanic.com", then the databse username would be something like bobthemech386296. Note that all non-alpha characters were removed ("." and "-").
Password: The password will be the same as your Database Manager password.
Database name: It will be the complete name of database as outlined in Creating a database.
