Why passphrases?

A 4-word passphrase from a 256-word pool has ~32 bits of entropy — comparable to a random 9-character password but far easier to type and remember.

Adding more words multiplies the combinations exponentially. 6 words gives ~47 bits — essentially uncrackable by brute force.

All generation happens in your browser. Nothing is sent to any server.
