I mean if you want family to have access to your accounts when you’re in a coma then you need to set up power of attorney beforehand. Or they can get a conservatorship.
My password file is not really a big concern if I’m in a coma as they’ll need other legal powers my passwords can’t help with. Even with passwords, they aren’t legally allowed to spend funds without power of attorney. And if they have power of attorney they can get passwords.
