Is Password Strength Checker free to use?

Yes, completely free with no hidden fees, limits, or registration required. Check unlimited passwords anytime.

How does the password strength algorithm work?

The checker analyzes 8 factors: length (minimum 8 characters), uppercase letters, lowercase letters, numbers, special characters, character variety, sequential patterns, and dictionary word matches. Passwords scoring 80%+ are rated Strong.

Does the tool store or transmit my password?

No. All password analysis happens locally in your browser. Your password is never sent to servers, stored, or logged. Your privacy is completely protected.

What makes a password strong according to this tool?

A strong password contains at least 12 characters including uppercase letters, lowercase letters, numbers, and special characters. Avoid sequential patterns (abc, 123) and common words. The tool rates passwords meeting these criteria as 'Strong.'

Does Password Strength Checker work on mobile devices?

Yes, fully responsive and works on all devices including iPhone, Android, iPad, tablets, and desktop computers. Use it anywhere with your web browser.

Can I check multiple passwords at once?

You can check one password at a time in the input field. Clear the field and enter a new password to check another one. Each check provides individual strength analysis.

What should I do if my password is rated weak?

Follow the specific recommendations shown: add more characters (aim for 12+), include uppercase/lowercase letters, add numbers and special characters, avoid dictionary words, and remove sequential patterns. Recheck as you modify it.

How long should my password be?

Minimum 8 characters, but 12-16 characters is recommended for strong security. Longer passwords with mixed character types are significantly harder to crack. This tool rates 12+ character passwords as strong.
