Default Password extractor!?

I would like to know is it possible to backup an apk that requires an account to be able to used with data for example: Pandora,Netflix,Facebook ect... I know all this can be done with titanium. But my question is there some kinda way that I could get the password for whatever apk with data I back up? Let's say I backup "netflix & data" so when I restore it, it will still have the account that I had it with. so I can still watch anything. Is there away that I could get that password from what titanium back up?
