Password Strength
Evaluate the resilience of your passwords against modern hacking techniques.
Frequently Asked Questions
Is my password stored anywhere?
Absolutely not. All checking happens locally in your browser using JavaScript. Your password is never sent to any server.
What makes a strong password?
At least 12 characters with a mix of uppercase, lowercase, numbers, and special characters (e.g. !@#$). Avoid common words or predictable patterns.
How to Use the Password Strength Checker
To check your password security, simply type or paste any password into the input field. The tool instantly analyzes it against six security criteria: minimum length (8 chars), strong length (12 chars), uppercase letters, lowercase letters, numbers, and special characters. A color-coded strength bar visually represents the overall score from 'Very Weak' to 'Very Strong', while a checklist shows you exactly which criteria you're passing or failing.
