      What Makes a Password Strong?

      How long should a password be?

      At least 12 characters. Every extra character makes brute-force attacks exponentially harder. A 16-character password takes billions of years to crack versus seconds for a 6-character one.

      Is my password sent to your server?

      No. This tool runs entirely in your browser with JavaScript. Your password never leaves your device and is never stored or transmitted anywhere.

      What's the safest way to manage passwords?

      Use a password manager like NordPass or Bitwarden. Never reuse passwords across sites — if one site gets breached, attackers try your password everywhere else.

      Why avoid dictionary words?

      Hackers use wordlists with millions of common words, names, and phrases. "P@ssw0rd" is in every attack dictionary. Random characters or passphrases are far safer.
