Hi, thanks for your feedback! Yes at the moment you can only change the password length via updating the config.py. This can only be done if you clone the repo and update the config.py yourself, not through installing off of PyPI. One of my first goals on the roadmap is to make configuration accessible to the user through the CLI, so they can change the generated password length, session time and colour scheme of the output. If you'd like I'd very much welcome a pull request if you want to help contribute to the project! Otherwise, I'll work on getting user configuration setup as a priority for the next release.
