Stronger credentials, fewer breaches

Reused and short passwords are behind most account takeovers. A long random password or a multi-word passphrase raises the cost of a brute-force attack far beyond what attackers will spend. This generator uses your browser's cryptographic random number generator, so the output never leaves your device.

What this tool gives you

  • Random passwords with control over length and character sets, including an option to drop look-alike characters.
  • Readable passphrases built from a word list, with separators, word casing, and an optional number.
  • A live entropy estimate in bits so you can see how strong each result is before you use it.
