Gpwg is a command line utility that generates strong, secure passwords that are accepted by all password inputs. It can be installed using pre-compiled binaries or with the Rust package manager, Cargo.
$ gpwg
> NMc@8ciaPyoH8WbSkU
$ gpwg --strong
> FV8QSMBR-amZhCNb-KLjKgBa-b2328cM
$ gpwg --entropy=256
> LKNTqNS3-4CBeAJy-9g2MxPv-WYMG9yP-t9wAZT8-X8amqaY-buE@uXR
$ gpwg --length=8
> A@q4PnLE
$ gpwg --copy
> Generated password sent to the clipboard. Clear & exit with Ctrl-C.

You can find pre-compiled binaries for Windows, Mac and Linux on the latest release
First, download and install rust. Then, use Cargo to install gpwg.
$ cargo install gpwg
GPWG passwords have the following properties:
- 100bit of entropy by default (strong enough for most use cases)
- Accepted by all password inputs
- Always include uppercase and lowercase letters, numbers and special characters
- No confusing sequences of characters (
1IlO0, key repeats, etc.) - No dictionary words or common password patterns
- Maximum score on the zxcvbn password checker
- Generated offline
- Always start with an uppercase letter to prevent mistyping on smartphones
- Special characters
!@are easy to type on most on-screen keyboards, do not interfere with text encoding, and are accepted by most password inputs with special character restrictions. - Compliant with NIST, Microsoft, IBM, ANSSI, CNIL guidelines
In case 100bit of entropy is not enough, the --strong option generates a longer
password with 160 bits of entropy suitable for cryptography. If 160 bits are still
not enough, the --entropy option allows you to specify an arbitrary entropy target.
By default, the password is printed to standard output. If you are in an environment where someone
might be able to see your screen or terminal logs, the --copy option can be used to copy the password
to the clipboard. The clipboard is automatically cleared when you exit gpwg with Ctrl-C.
