What is Passphrase?

A diceware passphrase generator: each word is chosen with crypto-safe randomness from a fixed 7776-word list, yielding ~13 bits of entropy per word.

How it works

Word count is clamped to 1–20; each word is picked via crypto.getRandomValues and joined with your chosen separator.
