Assorted

Github repos with word lists of varying sizes:

• LaTeX Diceware: https://github.com/ospalh/latex-diceware
• Iambic Mnemonic: https://github.com/ChristopherA/iambic-mnemonic/tree/master/word-lists
• Orchard Street: https://github.com/sts10/orchard-street-wordlists
• Sam Schlinkert: https://github.com/sts10/generated-wordlists
• Webpassgen: https://github.com/atoponce/webpassgen/tree/master/lists

Deliberately obsscure:

These lists aren't designed for building passphrases, but I use them in Passgen3 as something to be difficult to type, increasing your typing latencies and increasing the risk of typos, thus increasing entropy in your typing behavior.

You can see the combined lists here: https://github.com/atoponce/passgen3/blob/main/js/obscureWords.js

Not a huge deal, but my Orchard Street Medium list now has 8,192 words. I still maintain a 7,776-word list though.
