Strong passwords you can actually trust

How can you trust a password generator that runs on someone else's server? You can't really know it isn't logging what it creates. This one is different: it generates everything locally in your browser using the Web Crypto API (crypto.getRandomValues) — a cryptographically secure random source. Nothing is transmitted, logged, or stored. You can even turn off your internet and it still works.

🎲

Truly random

Uses your device's cryptographic RNG — not the weak Math.random() many tools rely on.

Memorable passphrases

Generate XKCD-style word passphrases that are strong yet easy to type.

What makes a strong password?

Frequently asked questions

Is the password sent to a server?

No. Generation happens entirely in your browser. The password never leaves your device.

How random is it?

It uses crypto.getRandomValues, the browser's cryptographically secure generator, with rejection sampling to avoid bias.

Are passphrases safe?

Yes — a 4-word random passphrase has strong entropy and is far easier to remember and type than a random symbol string.

What's a good length?

16–24 characters for random passwords, or 4–6 words for passphrases, covers virtually all needs.
