Common commands

pwgen

A strong 20-character password.

pwgen -l 32 -c 5

Five 32-character passwords at once.

pwgen -x -u -b

Exclude ambiguous chars, no repeats, begin with a letter.

pwgen --no-symbols

Letters and digits only.

pwgen passphrase -w 6 -C -d

Six capitalized words plus a random digit.

pwgen check 'mypass'

Estimate a password's strength (entropy + label).

echo -n secret | pwgen check

Read from stdin — keeps it out of shell history.

pwgen --copy

Copy straight to the clipboard.

Run pwgen --help (or pwgen <command> --help) for every option. Secrets print to stdout and entropy/status to stderr, so pwgen | pbcopy stays clean.

Why you can trust the CLI too

• Same audited core. Randomness comes only from Web Crypto with unbiased rejection sampling — never Math.random(), never modulo bias.
• Fully offline. A CLI makes no network calls. --copy shells out to your OS clipboard tool; nothing is sent anywhere.
• Open source. The whole package is small and dependency-light — read every line on GitHub.
