I'm pleased to know that you have resolved the problem. As is usually the case, the act of thinking how to explain the problem in a forum post sets off a background process in the brain . . . and some minutes later the solution becomes "visible".
As for the password, that can be absolutely anything you can type on the keyboard. The absolute simplest is one space character. Using just a space character makes the saved password appear to be null but, of course, it isn't.
