Where does the randomness come from?

A password is only as strong as the randomness behind it. Passwords derived from predictable patterns or a weak PRNG can be guessed or brute-forced far faster than their length suggests.

This generator reseeds your browser's CSPRNG with bytes pulled from Galactropy's physical entropy pool, radio noise conditioned through SHA-512, before assembling the password locally, so the character selection isn't driven by a predictable algorithmic seed alone.

⚠ Cryptographic notice

For SSH keys, RSA key pairs, or cryptocurrency wallets, don't rely on a password generator alone: mix external entropy with your local system source (`/dev/urandom` or `crypto.getRandomValues()`) using dedicated key-generation tooling.

Frequently asked questions (FAQ)

How long should my password be?

For most accounts, 16+ characters mixing letters, digits, and symbols is a reasonable minimum; for anything protecting sensitive data, longer is better. Length matters more than complexity rules once you're past a basic character set.

Are generated passwords stored anywhere?

No. Password assembly happens in your browser after fetching entropy seeds; the server never sees, logs, or stores the finished password.
