Passphrases you can remember.
Random words are easy to type and hard to crack. Pick how many words and how they're joined.
How it works
Words are picked from the EFF large wordlist of 7,776 words using your browser's cryptographically secure random generator. Each word adds about 12.9 bits of entropy, so five words give roughly 64 bits and six words about 78 bits.
The strength comes from the random choice, not from the words themselves — an attacker who knows the exact wordlist and settings still has to search every combination.
FAQ
How many words should I use?
Five words is a good minimum for most accounts. Use six or more for important passwords such as your password manager's master password or your email.
Is a passphrase better than a random password?
Not stronger per character, but much easier to remember and type. For passwords you store in a password manager, a random password is fine; for the few you must memorise, use a passphrase.
Should I add numbers or symbols?
They add a little strength and help with sites that require them, but adding another word adds more. Turn on the number option if a site insists on digits.
