About This Tool

The Password Strength Tester evaluates the entropy and security of your passwords by analyzing length and character variety. It uses industry-standard algorithms to estimate crack time and provides real-time feedback to help you create stronger, more secure passwords. All analysis happens locally in your browser — your passwords never leave your device.

How to Use

  1. Type your password into the 'Enter Password to Test' input field. The strength meter updates in real-time as you type.
  2. Review the metrics displayed below: Strength label, Entropy (bits), Estimated crack time, and Score (0-100).
  3. Use the feedback to improve your password — increase length and add more character variety (uppercase, lowercase, numbers, symbols) for higher strength.

Frequently Asked Questions

Is my password stored or transmitted?

No. All password analysis happens locally in your browser. Your password is never sent to any server or stored anywhere.

What makes a password strong?

Strong passwords are long (12+ characters), mix uppercase, lowercase, numbers, and symbols, and avoid common words or personal info. Entropy above 70 bits is considered secure.

Does it check against known data breaches?

No. This tool only evaluates entropy and estimated crack time. It does not query any breach databases.

Can I generate a strong password here?

This tool tests strength but does not generate passwords. Use a dedicated password generator or UUID generator to create random secure passwords.
