A passphrase trades character-by-character randomness for word-by-word randomness — often easier to remember and type, and still very strong if you use enough words. This tool shows the exact entropy of your word list so there's no guesswork.
Create several passwords at once using the settings above — useful for provisioning multiple accounts.
Type any password to score it instantly. This runs entirely in your browser — nothing is sent anywhere, logged, or stored.
Each word from this generator's list adds a fixed, calculable amount of entropy — five or more words gets you into solidly strong territory.
Toggling in a random number meaningfully increases entropy for very little added difficulty in typing or remembering.
The strength of this method depends entirely on the words being genuinely randomly selected — a phrase you invent yourself is far more guessable than one this generator picks.
They can be, if they're long enough — entropy is entropy. A five-to-seven word random passphrase from a reasonably large word list is comparable to a long random character password.
Passphrases are generally easier to type accurately and remember, especially for passwords you need to enter manually rather than store in a password manager.
Five is a reasonable minimum for most accounts; use seven or more for anything highly sensitive, like a password manager's master password.
