Is writing down passwords something people do? I have countless passwords saved over >20 years and I don’t think I’ve ever recorded one to paper. I even checked a couple of popular password management solutions and they don’t seem to have “print” functionality.
Doesn't work well in office environments, but at home the local threat model is largely fine with this.
I've written down one: the master password for my Keepass database, along with instructions on how to get to and open that file. It's in a 'open if I'm no longer alive' envelope.
Yes, it's pretty common.
