Password Generator
Strong random passwords or memorable passphrases — with a live strength meter, entropy in bits, and crack-time estimate. Generated locally, never sent anywhere.

How to use
Choose Random password for maximum strength in the fewest characters, or Passphrase for something long but memorable (the correct-horse-battery-staple idea). The meter shows entropy in bits and a rough offline crack time so you can see exactly how strong each option is. Everything uses your browser's cryptographically secure generator and never leaves the page.
Tips
- Length beats complexity — every extra character or word multiplies the guesses an attacker needs.
- Aim for 80+ bits for important accounts.
- Passphrases are far easier to type on a phone or TV than a symbol soup.
