No kidding, this is what I do!  At home, I go in a closet to type in
my passphrase.  Passphrases are very hard to memorize: I use the
Diceware method which I find useful.  As I am paranoid too, I try to
memorize at least 9 words.

I was aware that mechanical keyboards were one of the most common
flaws in computer security, but I had no idea that footages of my eyes
might give away my passphrase! Gosh!

Indeed I do.
