SOAP Calls Failing - "One or both of Username and Password are invalid."

A little more info, maybe not helpful, if I make the call and do not supply the integrators key, the call returns with an account and the base URL. But then if I make a call to RequestTemplates using the base URL and “/dsapi.asmx” (in this case “https://na2.docusign.net/api/3.0/dsapi.asmx”), I receive "One or both of Username and Password are invalid." and if I make the call to RequestTemplates and don’t provide the Integrator’s Key, I receive "The specified Integrator Key was not found or is disabled."

OK, so after doing the thing with not using the Integrators Key for the Login, my Apps & Keys dashboard now shows, “This app has used legacy authentication in the last 10 days.”, so it looks like the problem is that I need to use “App Password authentication” and the way it was being done has been deprecated. I just don’t know why I didn’t get any notice of that, I obviously need to get on that after this. I also noticed my key is listed as in the “Development” environment and there is a link to complete details to “Go Live”. Would that affect anything? I have a cert of compliance review and enabled in production from 2013. Would that maybe have been demoted bc of the legacy authentication (even though moving to App Password authentication would not have any effect on code)?

Can someone tell me why my key is not in production anymore and whether I should go through the steps to move that into production?
