But with transformer models it would probably be trivial to predict the top 10 next words if your passphrase is grammatically correct. Interesting password crac

  Done correctly, you choose words (uniformly) randomly from some dictionary, so the best a model can do is predict that all words from the dictionary are equally likely. All a model does is approximate probabilitly distributions, but the distribution isn't a secret; it's uniform. The dictionary doesn't need to be a secret either. The strength comes from the dictionary size and number of words.

    But the parent comment I responded to used the example passphrase “touch-some-grass” which is most definitely not a uniform distribution of words. Yes, done correctly this is secure.
