hackerxphantom/Facebook_hack ? reverse-engineered prompt

Build me a safe educational Python tool that demonstrates how password guessing attacks work without targeting real accounts or websites.

I want it to feel like the current script, with a simple terminal flow where I can enter a test user, load a wordlist, and see the guesses try against a local mock login page or a fake demo account I control. Please keep it easy to run on Windows, Linux, Termux, and macOS, and make the setup straightforward. If you need to, look up current docs online for anything related to running Python scripts cleanly across platforms.

Please also add clear warnings and a short explanation of why brute force attacks are harmful, plus an option to use a built in sample wordlist for practice. Make it polished enough that someone can learn from it, but do not include anything that targets Facebook or any real service.
