What is Diceware

Diceware passwords are generated by rolling a set of five dice together generating a five digit number which translates to a corresponding word or sequence of characters from a predefined list. Users can roll dice multiple times to generate multiple words and choose easy to remember words generated randomly from the dice roll. These words can then simply be concatenated or used as separated by spaces. Its recommended to use at least six or more words for better security.
