So, I want to prepare an instruction for my family in the case I'm dead, in coma or something similar. This document will need to contain (or point to) passwords, but also services which need to be paid, things which need to be done on a regular basis, etc. Of course, I don't want to have my passwords lying around in plain text (although a sealed envelope would probably be a reasonable compromise). Do you have any good practices/suggestions here? Note: while my family is not very tech-savvy, we have friends who are (and who would be willing to help if need arises), so I am (for example) strongly considering using a secret sharing algorithm.
