What this tool does not do / Limits
Words come from a built-in 32-word list on this page. A 4-word passphrase from a small list is not as strong as a longer one from a larger list, so use more words for important accounts.
Frequently asked questions
Where do the words come from?
A built-in 32-word list on this page. Nothing is downloaded and nothing is sent.
Is a 4-word passphrase enough?
It is about 20 bits from this list, so use more words for anything important.
