Frequently Asked Questions
How many words should I use?
With this generator's word list, use at least 6 words (about 66 bits) for ordinary accounts and 7–8 words (77–88 bits) for a password-manager master password or disk encryption. Four words is only about 44 bits, which a fast offline attack can exhaust.
Is a passphrase as secure as a random password?
With enough words, yes. Each word from our 2,049-word list adds about 11 bits, so 4 words give about 44 bits and 7 words about 77 bits — roughly the same as a 12-character random password using all character types. See passphrases vs passwords for the full comparison.
Should I use real words or made-up words?
Real words are fine if you use enough of them. The randomness comes from the word selection, not the words themselves.
Can I modify the words?
You can add numbers or symbols, but remember that modifications make passphrases harder to remember.
Where should I use passphrases?
Passphrases work well for master passwords, encryption keys, and passwords you need to remember. Use random passwords in a password manager for other accounts.
