xkcdpass is a password generator inspired by the famous xkcd 936 a webcomic, which shows a method on how to create passwords easy to remember for a human, but hard to crack using nowadays computers. In fact xkcdpass is the lazy version of the EFF dice generated passphrases method, it is using the EFF word files to generate a passphrase, but with a random generator algorithm. For real random passphrases use the EFF dice method.

xkcdpass generates following passphares without additional options. The passphrase has 6 short words like in example below:

Consulting -h the help file is a clever thing to do:

xkcdpass --help
usage: xkcdpass [-h] [-w WORDFILE] [--min MIN_LENGTH] [--max MAX_LENGTH]
                [-n NUM_WORDS | -a ACROSTIC] [-i] [-v VALID_CHARS] [-V]
                [-c COUNT] [-d DELIM] [-s SEP] [-C CASE] [--allow-weak-rng]

optional arguments:
  -h, --help            show this help message and exit
  -w WORDFILE, --wordfile WORDFILE
                    Specify that the file WORDFILE contains the list of
                    valid words from which to generate passphrases.
                Provided wordfiles: eff-long (default), eff-short,
                        eff-special, legacy, spa-mich (Spanish), fin-kotus
                    (Finnish) ita-wiki (Italian), ger-anlx (German), nor-
                        nb (Norwegian)
  --min MIN_LENGTH      Generate passphrases containing at least MIN_LENGTH
                        words.
  --max MAX_LENGTH      Generate passphrases containing at most MAX_LENGTH
                        words.
  -n NUM_WORDS, --numwords NUM_WORDS
                        Generate passphrases containing exactly NUM_WORDS
                        words.
  -a ACROSTIC, --acrostic ACROSTIC
                        Generate passphrases with an acrostic matching
                        ACROSTIC.
  -i, --interactive     Generate and output a passphrase, query the user to
                        accept it, and loop until one is accepted.
  -v VALID_CHARS, --valid-chars VALID_CHARS
                        Limit passphrases to only include words matching the
                        regex pattern VALID_CHARS (e.g. '[a-z]').
  -V, --verbose         Report various metrics for given options.
  -c COUNT, --count COUNT
                        Generate COUNT passphrases.
  -d DELIM, --delimiter DELIM
                        Separate words within a passphrase with DELIM.
  -s SEP, --separator SEP
                        Separate generated passphrases with SEP.
  -C CASE, --case CASE  Choose the method for setting the case of each word in
                        the passphrase. Choices: ['alternating', 'upper',
                        'lower', 'random', 'first', 'capitalize'] (default:
                        'lower').
  --allow-weak-rng      Allow fallback to weak RNG if the system does not
                        support cryptographically secure RNG. Only use this if
                        you know what you are doing.

Easy to remember passwords. 5 generated random examples to show the possibilities of passphrase creations:

This is using the xkcdpass default settings, it takes 6 words with the default settings.

Useful tool for generating passphrases. Really long passwords that are easy to remember for a human.
