Battle.net Authenticator Icon Re-design

So I decided to redesign the app icon for the Battle.net Authenticator to better fit with the iOS 8 system apps on my phone's home screen where it is located for quick access. (Too much Diablo, too little work!)

To describe the appearance of the icon I choose to feature the main purpose of the app in the icon's design. The icon displays the authenticator window with the code "123456" on it. Along the bottom of the authenticator window is the green expiry line, which tells the user in the app how long the code can be used before expiring. The padlock is purely because the app is used to unlock a B.net account. :)
