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.
