xkcdpass [-n count] [-d delimiter] [-w wordlist] [options]

xkcdpass generates memorable passphrases using random words. It's inspired by XKCD comic 936 about password strength.
Random words from a dictionary create passphrases. Four or more random words provide strong security while remaining memorable.
The default wordlist contains common English words. Custom wordlists can be used for different languages or specialized vocabularies.
Entropy information shows passphrase strength. Longer passphrases and larger wordlists increase entropy.
Acrostic mode generates passphrases where first letters spell a word. This aids memorization while maintaining randomness.
Word length filters exclude very short or long words. This can improve pronounceability and typing speed.

Security depends on wordlist size. Short wordlists reduce entropy. Random selection must be truly random. Not for high-security needs without verification.

xkcdpass was created inspired by XKCD comic 936 by Randall Munroe. The comic demonstrated that random word passphrases are more secure and memorable than complex but short passwords.
