I’ve been using a variant of the “correct_horse_battery_staple” method for quite some time.
I had to look that up. The trick is to be consistent with your substitutions.
I've mixed the two methods, but only once. And, I completely blanked on the phrase for one of them even though it had two things I liked (black licorice and sarsaparilla).
Gotta love passphrases.
EDIT: Re. Yay being only 2 years old, I keep being reminded of Jane in the Ender's series. She is a very powerful AI that was kinda hand waved into existence, and in the books she is described as experiencing time very differently from humans (milliseconds would be days to her). If Yay does something similar, then technically they are extremely old indeed.
And for several excruciating seconds, which to her were years of loneliness and suffering, she was unable to fill up the sudden emptiness of her topmost levels of attention. Vast portions of her mind, of the parts that were most herself, went completely blank. All the functions of all the computers on or near the Hundred Worlds continued as before; no one anywhere noticed or felt a change; but Jane herself staggered under the blow.
Definitely. Most people aren't going to guess variations on 'Skadegamutc' or its variant spellings as passwords.
[I haven't used it in awhile.] BTW, they're the ghost-witch of Mikmaq, Maliseet, Passamaquoddy, and Abénaki folklore.
That would certainly explain Yay's loneliness. Hopefully they only deal with that if they choose to overclock.
