Password Hardening Recommendations:
Free online Password Strength Checker. Audit password complexity and estimate crack time instantly.
Passwords are your first line of defense. Our password strength analyzer computes character entropy, scans for common dictionary words, and estimates brute-force time requirements to deliver precise security feedback and hardening tips.
How to Use
Type your password into the input field (toggle the eye icon to show/hide it). The security gauge updates dynamically alongside entropy statistics and specific improvement recommendations.
Key Benefits
- Real-time complexity analysis and entropy score tracking
- Mathematical brute-force crack time estimates
- Specific, actionable tips to harden weak passwords
- Runs 100% locally in browser to ensure your secrets stay secret
Frequently Asked Questions
Do you log or store my password during audit?
Never. All parsing, validation, and entropy computations occur inside your local browser sandbox. Your password is never transmitted across the internet.
How can I construct an extremely strong password?
Aim for at least 12-16 characters. Use an unpredictable mix of uppercase and lowercase letters, numeric digits, and special characters. Avoid using names, dictionary words, or simple sequential patterns.
