Frequently Asked Questions
Are passphrases as secure as passwords?
A 4-word passphrase has ~51 bits entropy (like a 9-char random password). A 6-word passphrase has ~77 bits (like a 14-char random password). Both are highly secure, but passphrases are much easier to remember.
How is the wordlist chosen?
Our wordlist contains 200 common English words chosen for clarity — no homophones (words that sound alike), no confusing spellings, no ambiguous terms. Mirrors the EFF Diceware selection principles.
Which separator should I use?
Use hyphen "-" for maximum compatibility with all services. Use space " " for natural readability if the service allows it. Avoid "." if the password might be parsed as a URL or filename.
Does capitalizing words make it stronger?
It adds ~1 bit entropy per word — minor increase. More useful for satisfying service uppercase requirements than for actual security improvement.
How many words do I need?
4 words = good for most accounts (51 bits). 5 words = important accounts like email (64 bits). 6 words = Very Strong, equivalent to a 14-char random password (77 bits).
