FAQ
How do I generate a memorable passphrase for free?
Choose how many words and a separator, and a passphrase generates instantly in your browser from a secure random source, with no upload — something like correct-horse-battery-staple that is easy to remember but hard to guess. The entropy in bits is shown so you know how strong it is.
Why are passphrases better than complex passwords?
A string of random words is both easier to remember and, with enough words, harder to brute-force than a short scramble of symbols. Length beats complexity, and this tool reports the actual entropy so you can add words until it is strong enough.
Is it generated on a server?
No — entirely in your browser, so the passphrase is never transmitted. It works offline.
How many words should I use?
Five or more for anything important; the entropy figure updates as you change the count.
Limits
Uses a compact built-in wordlist; entropy is reported honestly from its size. For maximum entropy, use more words.
