I know this'll sound odd. But even I don't know my own password.
It's like twenty eight or so randomly typed keys of just crap. Copy pasted onto a word file, copy pasted onto a flashdrive which I keep on me at all times. That's how all my passwords work. So even if you held me at gunpoint and demanded the password to my bank account. Iunno.
Seems weird, but it's worked for me for years. Can't keylog me because it's a copy paste, and glhf trying to hack the password for a single unsual.
That's actually a fantastic idea.
