"Simply, people can no longer remember passwords good enough to reliably defend against dictionary attacks, and are much more secure if they choose a password too complicated to remember and then write it down. We're all good at securing small pieces of paper. I recommend that people write their passwords down on a small piece of paper, and keep it with their other valuable small pieces of paper: in their wallet." (source)

"I claim that password policy should say you should write down your password. I have 68 different passwords. If I am not allowed to write any of them down, guess what I am going to do? I am going to use the same password on every one of them."

"Since not all systems allow good passwords, I am going to pick a really crappy one, use it everywhere and never change it. If I write them down and then protect the piece of paper--or whatever it is I wrote them down on--there is nothing wrong with that. That allows us to remember more passwords and better passwords."

"In general, passwords written on a piece of paper are more difficult to compromise across the Internet than a password manager, Web site, or other software-based storage tool, such as password managers." (source)
