I wonder why passphrases fell out of style? If you remembered a series of random words like you were activating the freaking Winter Soldier, boom, 40+ characters!
Did they ever get into style. I use them, but I don’t know anyone else who does. And some sites make diceware passphrases harder to use by e.g. requiring you to add numbers, special characters or capital letters, or by banning spaces. Or by banning non-ASCII, which makes it harder to use diceware passphrases in other languagess than English.
If we take the EFF wordlist commonly used to generate passphrases, we have 7776 words. If we take ASCII alphanumerics and special characters we have about 92. Assuming we generate a NIST compliant password of 15 characters in length we get 92^15=2.8*10^29 of combinations. To get the same level of security (same number of combinations) using the EFF wordlist we need (log(2.8)+29)/log(7776)=29.45/3.9=7.6 around 8 words. If we assume the words are 7 characters long on average, plus the separators, we get 7*8+6=62 characters long. If we start to also include Unicode characters like other scripts or emojis (something I’ve recommended to others) the required number of words grows even more. I don’t know about you, but I can’t be bothered to type that all out every time, a password manager works for me.
my workplace makes us change passwords every 3 months and I don’t respect them so its the same password with the same number at the end -1 because I can’t be bothered. If I get hacked oh no ive dealt damage to a multi billion dollar corporation woe.
I have yet to see a sticky note password that was anywhere near NIST compliant lol.
NIST compliance is 15 characters. That’s it. No stupid cycling every three months. No stupid special characters.
Somebody finally read the XKCD comic.

I have a system of using month and year plus a common trailing string. My annoyance is that every year the last number on the year keeps moving.
