I'm genuinely curious why this needs to be done. Maybe I'm weird, but I don't think I have anything valuable online that my family would want. Of course, there are all my financial accounts, but I would think that just a password wouldn't do them much good with those, at least to legally drain them. I would think (and could be wrong) they would need to go through legal channels for that. What else is there? I can't imagine they want download my email which is mostly just business transactions anyway.
