A simple yet robust commandline random password generator.

Multiplatform (Linux, Mac, Windows). Fast.

You can use it generate keys or passwords in scripts or use it as your primary desktop password generator.

Has extensive generative test suite, including tests against a Rust port of Dropbox's password strength tester zxcvbn

#Typical usage

genpass                  # use defaults, they're good
genpass 2048             # generate long password, can be used as a key
genpass --passphrase 128 # generate longer passphrase
genpass -dlu             # no special characters

#Generating a password directly into your system clipboard

On a Mac:

genpass | pbcopy

On Linux:

genpass | xclip -selection clipboard


On a system with Rust installed:

$ cargo install genpass

#Commandline options

$ genpass --help

genpass [FLAGS] [length]

-h, --help                 Prints help information
-d, --include-digit        Include at least one digit
-l, --include-lowercase    Include at least one lowercase letter
-s, --include-special      Include at least one special (non-alphanumeric) character
-u, --include-uppercase    Include at least one uppercase letter
--passphrase           Create a passphrase of (at least) the given length instead of a password.

<length>    The length of the password to generate [default: 32]

#A note on passphrases

  • Passphrases are generated using EFF's "long" password list.
  • Passphrases are at least --length characters long, not necessarily exactly that long.

#A road to 1.0

TODOs to get genpass to 1.0
