A memorable password can combine four randomly selected words, balancing resistance to guessing with easier recall. A generator can draw from a word list or from cleaned literary text, then combine the selected words into one string. section 20.0
A practical password generator supports these controls:
- Choose the number of passwords and words per password. section 20.1
- Filter words by minimum and maximum length, remove non-characters, and title-case the retained words. section 20.1
- Use a random seed and sorted input so repeated runs produce testable, reproducible selections. section 20.1.6 section 20.3.5
- Optionally apply leet-style substitutions and append punctuation. section 20.1
Generating reproducible passwords
A command such as `./password.py --num 2 --num_words 3 --seed 9 sonnets/*` produces passwords like `QueenThenceMasked` and `GullDeemdEven`. Increasing the length bounds selects longer words, while `--l33t` produces mixed-case substitutions and punctuation such as `p3RsPeC+1Vesucces5i0niN+3lL1Genc3$`. section 20.1
$ ./password.py -h
usage: password.py [-h] [-n num_passwords] [-w num_words] [-m minimum]
[-x maximum] [-s seed] [-l]

Password maker
positional arguments:
FILE Input file(s)
optional arguments:
-h, --help show this help message and exit
-n num_passwords, --num num_passwords
Number of passwords to generate (default: 3)
-w num_words, --num_words num_words
Number of words to use for password (default: 4)
-m minimum, --min_word_len minimum
