I HAVE seen many discussions 'in the wild' about password strength. The best that you could do is test MaxLength for yourself, but many places recommend a passPHRASE
I have recommended picking a book from you bookshelf - all that you need do is remember the book
flip it open to a random page write down the page #
close your eyes and point to the page - count down the number of lines - write that number down
pick a string of words - then count to the first word - write that down
count the number of words in your chosen phrase - write that number down
you would have ONLY numbers recorded for your secret code (this is "spycraft", BTW)
137, 7, 3, 5 = put this StickyNote in your desk = no one would know what it means, even if found
use a "delimeter" instead of spaces and Initial cap each word & sprinkle in special characters = " This_Password_!s^In~Mac$peak "
If you ever have to change password, you can just pick another random page from the same book - or pick another
