Diceware
A method for generating strong passphrases by rolling physical dice to select words from a numbered wordlist.
Diceware is a passphrase generation method invented by Arnold Reinhold in 1995. Roll five six-sided dice, look up the five-digit number in a 7,776-word list, and the matching word becomes one element of the passphrase. Each word contributes about 12.9 bits of entropy, so a six-word Diceware passphrase delivers around 77 bits, which resists offline attack on a slow KDF like Argon2id. The appeal is that it produces memorable, pronounceable secrets without trusting any software randomness source.
