Password Generator
Cryptographically random passwords generated in your browser — they never touch a server.

How random are these?
Passwords are drawn from crypto.getRandomValues() — the browser's CSPRNG — using
rejection sampling to avoid modulo bias, so every allowed character is equally likely. A 16-character
password over the full 94-character set has about 104 bits of entropy; a 12-character one is
generally considered sufficient for most accounts when the site throttles guessing.
FAQ
Are these passwords stored or transmitted?
No. They exist only in this page's memory until you copy them.
Should I add a passphrase instead?
For memorized master passwords, diceware-style passphrases are often easier to remember at similar entropy. This tool targets generated secrets you store in a password manager.
