I have this for years, as a google docs shared with some people and a printout.

This is basic decency for the ones that remain and taboos should not be a reason to not do this.

It is a how to on hiw to connect yo my data, including butwarden (where the important logins are shared anyway), all banks, investment companies etc.

I also added a section on how to dumb down my smart home, but this is a niche case.
