For passwords I need to remember (rather than just putting in my password manager), I've taken to using lines from foreign content, especially if it's something I've translated myself or I've introduced some deliberate misreadings in. I imagine very few dictionaries would have "personawakokoronoka!" in them (not a password I've used, but illustrates the idea). Derived from: ペルソナは心の力 - read as "perusona wa kokoro no chikara" Then I've replaced it with the English spelling of Persona -> "persona wa kokoro no chikara" Then I replace chikara with a misreading - when I first learnt the characters, I mixed up 力 (chikara) with the katakana カ (ka) and often read both as ka -> "persona wa koroko no ka" Then remove the (unneeded) spaces and add a "!" for good measure -> "personawakokoronoka!" Dead easy for me to remember, but (I believe) difficult to derive/guess or dictionary attack (especially if I start with a longer sentence).
