So you replaced the letter “e” with “3” and capitalised a random letter, and now you think your password is secure? Nope. Hackers (and the NSA) know those tricks, too. That’s why you should use this crazy dice technique to create a practically unbreakable passphrase.
A passphrase is inherently more secure than a password. Since it’s often a series of words, it ostensibly offers more entropy, but since many people lift language from literature, computers can easily guess the phrase. Micah Lee just published a better path to security at the Intercept, one that uses dead simple dice-rolling to generate truly random passphrases.
The method takes advantage of the Diceware technique. You just roll a set of regular old six-side dice to generate a numerical phrase that you can then translate into a random word from the Diceware word list. The more words you generate for your passphrase, the more secure it becomes. And since it’s completely random, the passphrase becomes close to impossible for anybody or computer to guess.
