How to find log in credentials for Sage 50 database

I am trying to go through some of the code examples in the SDK, obviously one of the first functions that runs is the database connection function. I have tried sysadmin with various passwords but I can never successfully connect to the database to try they code. Any idea where I can find the credentials and/or reset them?

Specifically its the SDKInstanceManager.Instance.OpenDatabase() function where I run into the issue with username/password and looking through the c# example code.
