Frequently asked questions
Why use a passphrase instead of a random character password?
Several random words are genuinely easier to remember and type than a random character string, while still being hard to guess — each additional word multiplies the possibilities by nearly 7,776, so even a modest word count reaches strong entropy.
Where does the word list come from?
The Electronic Frontier Foundation's improved Diceware word list — 7,776 common, easy-to-spell English words specifically curated to avoid similar-sounding or hard-to-type entries.
How random is the selection?
It uses the Web Crypto API's cryptographically secure random number generator with rejection sampling to avoid bias, run entirely in your browser — the same class of randomness source used for generating encryption keys.
