DiceKeys will help you create a permanent strong password (video)

Modern computer security systemrequires the user to constantly create complex passwords, remember them, use completely different passwords for each website without repeating or writing them down. Even in the case of using a password manager, you have to remember an incomprehensible, long password and save it for years in order not to lose access to your data. However, cryptographer Stuart Schechter, a computer scientist at the University of California, Berkeley, proposed DiceKeys, a simple 25-dice set for physically creating a single, ultra-secure key that can serve as the basis for generating all of the most important passwords in your life over the years.

DiceKeys is a simple plastica device similar to the game Boggle, and a special application that allows you to scan the result of throwing 25 dice. The resulting key can be used directly to create a password, or used to obtain master passwords for password managers, as a seed to create a U2F key for two-factor authentication, or even as a secret key for cryptocurrency wallets.

You just need to roll the dice, said onPresentations Schechter, offering crowdfunding kits for $ 25, for January delivery. In fact, you just need to shake the cubes in your purse, pour them into a plastic box, turning one of the faces with the symbols up and close it with a transparent lid. Then the result of the throw should be scanned using the application for further password generation according to the barcode principle. A special application is created in such a way that data from a smartphone never leaves the device.

According to the inventor of the eternal passwordSchechter, due to the placement of various numbers and letters on the surface of the cubes, as well as due to the different orientation of these surfaces, about 196 bits of entropy are created. This means that the selected password is one of 2 to 196 power options for generating passwords using this set. This number, according to Schechter, is the number of atoms in four or five thousand solar systems. With modern technology, it is impossible to create a computer powerful enough to guess this number.
