I mean. I have a little book on my desk with password hints. "2nd grade best friends phone number", "birthday of first dog". It also has a grid of random numbers/letters on the front page, so I can write "first_crush_b4*5". You'd have to have physical access to the book, and know what the hint leads to. It's un-hackable. I mean aside from social, or physically breaking into my house.
downvote all you want, this is third time in a month that basically "opsec" failure would've been prevented by a password manager that binds to domains, or passkeys. Both of which people regularly kvetch about here.
