Are emojis going to replace pin numbers?

UK firm creates emoji-based passcodes that are more secure than traditional four-digit numerical pins " but don't get too yet

Could emojis be the future of online security? One company is claiming so, suggesting replacing four-digit passcodes with a four-digit emoji string would be almost 500 times more secure. So should we ditch or pins for smiley faces?

The British start-up at the heart of the claims, Intelligent Environments, trumpets numerous other benefits as well. It cites "memory expert" Tony Buzan, who says that an emoji passcode "plays to humans' extraordinary ability to remember pictures, which is anchored in our evolutionary history".
