My mom told me that she was made fun of for having a book of hand written account credentials related to running her business (6 people total). I told her it was the best way to do it that wasn’t massively overcomplicated for her situation and to keep it up. The only recommendation I made is that she use different long passwords for every site since she’s already not memorizing them.

Personally I’m not convinced this isn’t the best way unless you’re being targeted by physical bad actors
