This is a Wrong Pincode Filled icon. We've made it in iOS style, first introduced in iOS version 7 and supported in all later releases up until now (at least iOS 11). This style is based on thin two-pixel lines and is optimized for 50x50 px. Unlike other vector icon packs that have merely hundreds of icons, this icon pack contains 12,700 icons, all in the same style and quality.
The logo shows two shapes indicating that you entered the wrong code. The shape on top is a long rectangle with four small circles in it, such as the diagram you see when you type in a PIN at an ATM. The shape below it is a circle with an X through it, denoting that it is incorrect.
