Most supported softwares have an administrative web interface.
Selecting the Display Admin UI button will display the URL, user name and password used to connect to a service's administrative UI.
Some software, especially databases, do not have a web management UI. Use the credentials, and the specified port to connect.
Certain applications do not allow for the pre-creation of administrative users. If the password field appears blank in the service dashboard, visit the given administrative URL to begin the setup process.
