Re: No it doesn't
At home, that will work very well... unless you have unwelcome visitors. Even then... maybe not a problem. They'll steal the computer and ignore the Post-It notes.
At work.. I use a small notepad that's kept in a locked drawer. (We're not allowed to put a PW manager on company machines). I note that many (most) of the employees do the same notepad kept away from prying eyes thing. But there's a few who use Post-It notes... usually managers who won't listen to the reality of locking those away. Go figure...
KISS works for most of us.
