UK firm Intelligent Environments has a concept for an emoji alternative to PIN passwords. 

The firm claims that the emoji passwords are not only easier to remember, but “mathematically more secure.” It also quotes “Memory expert Tony Buzan” as saying: "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.”

As of yet, there are no banks affiliated with the firm or its emoji password.
