A person-woman-man-camera-TV just announced his new creation - DiceKeys. The point is that you roll a set of 25 special dice, each with 6 sides I presume, that will land in a truly random pattern that can be scanned using a custom application, that will then interpret the orientation and faces of these dice and generate a master key with lots of entropy, about 2¹⁹⁶. That is the same entropy of an alphanumeric password of 33 characters [a-z, A-Z, 0-9] which is 62³³.

But why overcomplicate something already so confusing to most people as good security? He claims you can place a lid on the box and preserve the layout of the dice as a secure way to store your dice keys.

However there is absolutely no added security compared to writing a secure 33 character password on a piece of paper and storing it where you would have stored the DiceKeys. Ink will last a long, long time. As far as getting a good secure password? Easy. If you really want to use a mechanically random method, write the letters a to z, A to Z and 0 - 9 on small pieces of paper. Toss them in a basket. Cover the basket and shuffle them by shaking the basket. With the cover on, pick a piece of paper. Write it down, return it and repeat 32 more times. There is your person-woman-man-camera-TV über secure password.
