Diceware is a method where users roll dice and reference a word list to create unique passphrases.

Note: This activity happens in a public setting. We advise you NOT to use you diceware passphrase from this session, but you roll your own diceware phrases in a private and secure environment.

Generate the numbers:

1. Roll your die five times to create a 5-digit number
2. Write down the 5-digit number on your handout
3. Repeat steps 1 & 2 until you have a total of six, 5-digit numbers

Find the words:

1. Go to https://www.eff.org/files/2016/07/18/eff_large_wordlist.txt
2. Use [CMD/CTRL + F] to find your number in the list
3. Write down that number’s corresponding word on your handout
4. Repeat steps 2 & 3 for all of your numbers until you have 6 words
