Frequently Asked Questions

How long should a strong password be?

NIST 800-63B recommends a minimum of 8 characters but encourages 12-16 for sensitive accounts. A 16-character mixed-case alphanumeric password has roughly 95 bits of entropy, which would take quintillions of years to brute-force at 1 billion guesses per second.

Where does the randomness come from?

The generator uses window.crypto.getRandomValues(), which pulls from the OS's cryptographic RNG (CryptGenRandom on Windows, /dev/urandom on Linux/macOS). This is cryptographically secure, unlike Math.random(), which is unsuitable for passwords or keys.

Should I include symbols in every password?

Yes when allowed, but some sites silently reject characters like $ or & through poor input validation. If a generated password fails to save, regenerate with the symbols toggle off rather than truncating. Length contributes more entropy than character variety beyond about 12 chars.
