Password Strength Checker

How is Password Strength Calculated?

This tool uses zxcvbn, a realistic password strength estimator created by Dropbox. Instead of blindly requiring uppercase/symbols, it recognizes common patterns like names, dates, dictionary words, and keyboard layouts (like "qwerty"). It then calculates the entropy and the estimated time it would take a hacker to crack it using dedicated hardware.

Is it safe and private?

Yes, absolutely. All processing is done locally within your web browser using JavaScript. Your data is never transmitted to or stored on our servers, ensuring 100% privacy and security.
