@kev The problem with "password on a post-it" was traditionally office environments, if I recall my 90's/00's correctly. People overgeneralized that to "never commit a password to paper" which is just... wrong? Like, I definitely have my key passphrases recorded on paper, because if I get hit by a bus my wife is going to need access to my files. The paper is just not in a very obvious place. :-)
I think even my credit union gets it: They said not to store my password in a Word document. :-)
