>One alternative is to use them like mnemonic code phrases. So perhaps your answer to "What's your favourite animal?" is not really an animal, but maybe Cthulhu, so maybe the answer would be "Ph'nglui mglw'nafh Cthulhu R'lyeh wgah'nagl fhtagn"
I'd go further than that and use stuff like that for actual passwords, but with a twist.
Using that sort of thing for such questions is good, but take something you know well, like a song lyric or line from a poem and then change it subtly. For example:
Forty score and eleventy years ago, our
foremothers brought forth a new abomination.
Since
you're the one making this stuff up, it's easy to remember, both for passwords and for those "secret" questions.
Those are pretty much endless in possibility too:
In the town where babby formed, there lived a
gal who mailed some trees.
Ask not what who has done it in your country.
Ask which Lulu can do it with you.
And on and on. The only real requirement is that
you know whatever it is you're adapting well. Whether that be song lyrics, movie lines, poesy, etc.
I prefer song lyrics myself, since they're usually easier to remember, and when presented with the need to recall it as a password/"secret" question, the modifications made come right back.
I imagine that wouldn't work for everyone, but it works well for me, and would also work for others.
Good luck!
