    How to generate a Diceware passphrase

    For each word, roll five six-sided dice in order and enter the five digits. The resulting number points to one entry in the EFF long word list. Browser mode performs equivalent independent selections with the Web Crypto API.

    How many Diceware words should you use?

    Every independently selected EFF word contributes about 12.9 bits. Six words provide about 77.5 bits. Your requirements may differ, so increase the word count for especially valuable credentials and store the result securely.

    Diceware is not a crypto recovery phrase

    This tool creates passwords and passphrases. It does not implement BIP39, SLIP39, checksums, wallet derivation, or any cryptocurrency recovery standard. Never use its output as a wallet seed phrase.

    Keep the selection random and unique

    Do not reroll merely because you dislike a word, and do not substitute related or memorable words. Use each generated passphrase for only one account. For a conventional password, use the random password generator.
