- Hit generate until you find one you like, then copy it.
Why passphrases beat passwords
A four-word random passphrase like "correct horse battery staple" has about 44 bits of entropy — comparable to a random 8-character password — but is dramatically easier to type and remember. The key word is random: your brain is terrible at randomness, so let the generator pick. Never reuse a passphrase across important accounts; pair them with a password manager so each site gets its own. If a site forces symbols and numbers, the options here cover that without weakening the core idea. And treat a passphrase like a password: never share it, never email it to yourself, and enable two-factor authentication wherever it matters.
Frequently asked questions
Are passphrases really secure?
Yes — a random 4-word passphrase from a 2,000-word list has roughly 44 bits of entropy, strong against guessing attacks. More words means more security.
Why not just use a sentence I make up?
Human-chosen phrases are predictable. Attackers use dictionaries of common phrases, so true randomness from a generator is much safer.
How many words should I use?
Four words is good for most accounts; five or six for your email and password manager — the keys to everything else.
Is my passphrase sent anywhere?
No. Generation happens entirely in your browser with cryptographic randomness. Nothing leaves your device.
