Diceware is a method for creating passphrases using gaming dice. It is one of the best ways of choosing a strong password/passphrase, due to the randomness of the dice throws. The chosen words in the passphrase are found by obtaining a number five digits in length by throwing a dice five times, after which the word corresponding to the number is taken from the Diceware dictionary. For example, the number 11135 corresponds to the word ‘abbey’. All other numbers correspond to different words.

This process is repeated for a given number of words, although more words result in a stronger password. The process creates a strong password because the words are unlikely to have any relation to each other. This means that the passphrase will have a high degree of entropy, one of the most important factors in creating a strong password.
