PassGen — secure password and passphrase generator

PassGen builds strong passwords and passphrases entirely inside your browser. Randomness comes from crypto.getRandomValues, the browser's cryptographically secure generator; nothing you generate is transmitted, logged, or written to storage.

Two modes:

Random characters — choose the length and mix in uppercase letters, digits and symbols. Lowercase is always included.
Passphrase — words drawn from the EFF Short Wordlist #1, joined by a separator of your choice, for something you can actually type from memory.

The session history lives in memory only and dies with the tab. PassGen needs JavaScript to run — please enable it.
