What do you need to leave written if something happens?

> What do you need to leave written if something happens? This question is what I've been raising to family and friends in an eventual situation where they are unreachable for a long time. The reasons can vary, either from a longer-than-expected vacation, a disease, an accident, or ultimately, death... It's not easy to answer, but almost everyone starts talking about their life insurance, the bank account that their family members may not know about; the Steam account full of skins, etc. I'm raising the question here too, not to know what you need to leave written, but to understand if this is something that comes up in your mind and if you'd be ready to deal with it! This is the reason why I decided to build [Albwer](https://www.albwer.com/) together with a friend. We both had this question in our minds. The goal of [Albwer](https://www.albwer.com/) is to be much more than a "dead's man switch". It should give lots of configuration possibilities, and give you almost full control, but while keeping a simple UX. Moving away from the darker image, these kinds of services usually entail. I'd like to hear your thoughts and opinions!
