Frequently asked questions

Why use words instead of random characters?

A passphrase like "correct-horse-battery-staple" is easier to remember and type than a string of random symbols, while still being extremely hard to brute-force due to its length.

Is this the same as a password manager?

No — this tool generates a passphrase but doesn't store it. For securely storing passphrases and other credentials with automatic delivery to family if you go silent, see Notenz's free vault.

Is anything sent to a server?

No. Passphrases are generated locally in your browser using the Web Crypto API's random number generator and the EFF's published wordlist.
