That is actually a secure form of challenge and with practice you can
memorise a password to recall individual characters without writing it
down.


I have (roughly) a dozen "important" passwords[1] & they are all
reasonably "strong".

You aren't really suggesting that I can hold all of them in memory & do
the necessary juggling each & every time I need access?


[1] I haven't attempted to count the other passwords, but it's well over
30.
