Password Strength Analyser

About Password Strength

This tool uses the zxcvbn library to estimate the strength of your password. It provides a score from 0 (very weak) to 4 (very strong) and offers feedback and suggestions to improve your password's security.

No password data is sent to any server; all analysis is performed locally in your browser. Aim for a score of 3 or 4 for good security. Consider using a password manager to generate and store strong, unique passwords.
