Why did it take so long for someone to think of this? A UK company called Intelligent Environments has come up with a way to use emojis as a password. While this may sound silly right of the bat. The science is sound. A four charter pin has 7,290 unique permutations of four non-repeating numbers. Emojis on the other hand when used as a four charter pin has 3,498,308 million unique permutations of non-repeating emojis. Not only are emojis easier to remember but the complexity of the emoji character set makes brute-force attacks harder to pull off. Before you get too excited, note that Intelligent Environments doesn’t seem to have is any banks or sites signed up to use concept.
The Emoji Passcode plays to humans’ extraordinary ability to remember pictures, which is anchored in our evolutionary history. We remember more information when it’s in pictorial form, that’s why the Emoji Passcode is better than traditional PINs.” ~Memory expert Tony Buzan
