Analyze password strength with detailed scoring and improvement tips
Enter a password to check its strength
Password Strength Checker is a free online tool that analyzes your password and provides a detailed security assessment. It checks length, character variety (uppercase, lowercase, numbers, symbols), common patterns, and estimates how long it would take to crack your password. The tool provides a score out of 100, a strength level from Very Weak to Very Strong, an estimated crack time, a security checklist, and actionable suggestions for improvement. Your password is never sent anywhere — all analysis happens in your browser.
