Dead simple password generator

Motus is a command-line application written in Rust that makes generating secure passwords a breeze.

Inspired by the user experience of the 1Password password generator, motus focuses on providing a simple and elegant user interface with sane defaults and comprehensive options. By default, motus copies the generated password to your clipboard, making it even more convenient to use.

Why the name?

motus used to be a tv game that I would call the ancestor of Wordle. Players had to guess words of a given size, and would pick up balls from a cup to decide how each round would move along. They would make that very distinct move to scramble the balls around every time, with a very distinct sound. When starting this project, I thought of the process of generating passwords as this comforting and satisfying act of diving into a huge cup full of numbered balls, and the childish feeling of it. This project is named in memory of Motus.
