Frequently asked questions
Why a passphrase instead of a password?
A handful of random words is far easier to remember than a string of symbols, yet can be just as strong: each random word from the list adds about 12–13 bits of entropy, so four or five words are very hard to guess.
Are the words chosen securely?
Yes — words are drawn with crypto.getRandomValues (unbiased), entirely in your browser, and the passphrase is never transmitted or stored.
