I guess my family will take care of my physical stuff. For the online part, some of it can probably be handled through support (facebook, etc...), and the rest will stay as is until it is deleted for lack of use. Or never deleted. Both are okay.

Leaving a physical trace of my passwords is not only bad practice from security point of view, but quite useless since I know them. Also, my online accounts are useless if I can't use them because I'm dead, so I don't really care if no one can access them anymore. What happens to important things such as banking is already dealt with.
