What is Password Strength Checker?
A password strength checker analyzes your password in real time to evaluate its resistance to cracking attempts. It checks for common patterns, dictionary words, and entropy to give you an accurate strength score. Use it to ensure your passwords meet modern security standards.
How to use
- Type or paste your password into the input field to begin the analysis
- Review the strength score, estimated crack time, and specific feedback about weaknesses
- Improve your password based on the suggestions until you reach a strong or very strong rating
Result
Enter 'Tr0ub4dor&3' to see it scores as moderate — while it uses mixed characters, it follows a predictable substitution pattern. Compare with a random passphrase like 'correct-horse-battery-staple' which scores higher despite using only lowercase letters and hyphens.
