I used to remember them all. Until I had 3 dozen of them that I use daily and had to be 16 characters long with a numeric and a special character somewhere in the middle (but, no '&'s) and needed to be changed every 30 days and couldn't be a different variation of my last 10 changes or use my initials or have any part of my name or username in them, etc... I have too much other cryptic non-intuitive stuff to remember now so they all stay in an encrypted file or in KeePass. Except for my Pelican password... I havent changed that one in 10 years
