Is this password checker secure?

Yes. All analysis happens locally in your browser. Your password is never sent to our servers, ensuring it remains completely private.

What does the strength score mean?

The score (0-4) is based on entropy, which measures a password's unpredictability. A higher score means it's more resistant to guessing and brute-force attacks.
