This is a simple password checker based on zxcvbn. It's simple, short program that you can use to easily check your passwords on a local machine, rather than using a website that promises it's definitely not storing your passwords.
The only main prerequisite is zxcvbn, which can be installed by either:
python3 -m pip install zxcvbn
or pip3 install zxcvbn
Then you simply need to execute the program. The program will ask you for a password, which you type into the terminal. It will keep looping, over and over, until you enter exit, quit, or stop as the password.
