If I'm not mistaken, they're stored in the registry, which makes this problematic. It might be possible, with little real difficulty, to find the right strings, export them, and import them. But it's not straight forward.

While I'd be willing to look at it, and help out -- you'll ultimately want to know what the credentials actually are. Perhaps a call to billing to confirm which email addresses are tied to which accounts and exercising the 'forgot password' feature would ultimately be a healthier activity.

And, as a caution, be aware that if you store your credentials, you increase the possibility of your information getting compromised. Not a great deal, mind you, but enough that you should consider it.
