A cross-platform desktop application for generating secure passwords and evaluating password strength, built in Go with Fyne.
- Password Generator — generate cryptographically secure passwords with configurable character sets (uppercase, lowercase, numbers, symbols) and length (8–128)
- Strength Checker — evaluate password entropy in bits with a visual strength rating
- Breach Detection — checks passwords against the Have I Been Pwned database using k-anonymity (your full password never leaves your machine)
- Go 1.21+
- A C compiler (required by Fyne for CGo):
- Windows: MSYS2 with the MinGW GCC toolchain
pacman -S mingw-w64-ucrt-x86_64-gcc
C:\msys64\ucrt64\bin to your system PATH.
- macOS: Xcode Command Line Tools (
xcode-select --install)
- Linux:
gcc via your package manager (e.g. sudo apt install gcc)
git clone https://github.com/qro/password.git
cd password
go run ./cmd/password

- This was a half finished project that was lying around on my computer, so I decided to finish it up and give it a lovely UI
- Some other ideas I have in mind for this project:
- Password manager tab
- Breach lookup tab
