A simple Python tool that checks how strong a password is, tells you if it has appeared in known data breaches, and can generate a strong random password.
Many people use weak or reused passwords, which is one of the biggest causes of hacked accounts.
To help users check their password strength, get tips to improve it, and create strong passwords safely.
- Strength checker: shows Weak / Moderate / Strong based on length, uppercase, lowercase, numbers and symbols
- Tips: tells you what to add to make the password better
- Breach check: checks if the password appeared in known data breaches (using the Have I Been Pwned API)
- Password generator: creates a strong random password
Your password is converted to a SHA-1 hash, and only the first 5 characters of that hash are sent to the API. The full password never leaves your computer (this is called k-anonymity).
- Install Python 3
- Install the requirement:
pip install -r requirements.txt - Run the program:
python passguard.py
