Password Strength Checker
Test password strength with entropy analysis and a top-1000 dictionary check — runs entirely in your browser.
Frequently asked questions
Is my password sent anywhere?
No. Everything runs entirely in your browser using JavaScript — there is no API call, no network request, and nothing is stored or logged. You can confirm this by opening your browser's network tab while you type. For full peace of mind you can disconnect from the internet and the tool still works.
What does the entropy estimate actually measure?
It estimates resistance to offline brute-force from password length times the size of the character set you used (lowercase, uppercase, digits, symbols), then translates that into a crack-time estimate at modern GPU speeds. It is a guide, not a guarantee: it does not catch dictionary words, predictable patterns like Spring2024!, or breach reuse beyond our common-password list, so a 'Strong' result can still fall to a targeted attack. The best practice is a long, unique passphrase per site stored in a password manager, with MFA enabled.
