Trusted connection means you are using your windows username/password that you logged in to windows with. You do not specify a username or password in the connectionstring - just that trusted_connection = True.

If you want to specufy a SQL username/password in your connectionstring, then do not include the Trusted_Connection parameter or set it to False.
