We have a "bottom drawer book". Passwords are in it, as is other information such as where wills and personal papers are kept, name of solicitor, funeral director, etc. The aim is to have information at the fingertips of whoever is left - there are only the two of us in this house; one son lives 720 kms away and the other is on the far side of the world. They wouldn't know where to lay hands on such information bit by bit, so it's all in one book. A "one stop shop", as it were.

There's nothing like being prepared, is there.
