Diceware

 

Diceware is a way to generate random word groups (passphrases) that are easier to remember, but because of their length contain sufficient entropy to make them secure. Diceware is based on the principle that truly random selection of words from a wordlist, can result in easily memorable passwords that are also extremely resistant to attack.

While very long randomly generated passwords controlled by a password manager are preferred, there are still some passwords / passphrases that you must memorize - such as the passphrase granting access to your password manager. This is where using Diceware is an excellent tool for generating that passphrase.

In July 2016, the Electronic Frontier Foundation (EFF) updated the original Diceware wordlist.  Passphrases are generated in the same manner using the EFF list as when using the original Diceware list, but the EFF corrected some issues with the original list that had potential to generate errors.

Consider Diceware and the updated EFF wordlist when you need to generate a memorable random passphrase.
