A passphrase strings several random words together, like maple-rocket-hollow-cobalt. It is far easier to type and remember than a jumble of symbols, yet a four-word phrase is very hard to crack. Choose how many words, a separator, and whether to capitalize or add a number.
Passphrases shine as the one password you have to remember by heart — a device login or a password-manager master key. Because their strength comes from length and true randomness rather than obscure symbols, they stay both strong and human-friendly.
Everything is generated in your browser with a secure random source and never sent anywhere. Add a word or two for extra strength; each random word makes the phrase dramatically harder to guess.
Frequently asked questions
Are passphrases actually secure?
Yes. A phrase of four or more randomly chosen words has enormous strength, and its security does not depend on you memorizing symbols and numbers.
How many words should I use?
Four is a solid minimum; five or six is stronger. Use more for anything protecting sensitive accounts.
Is it safe to generate one here?
Yes — words are chosen in your browser with a secure random source, and nothing is transmitted or stored.
