This is a Good Pincode 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 12,300 icons, all in the same style and quality.
There is a retangled that is shorter than it is wide with four dots equally spaced in the the center of it. Below the rectangle is a circle that is about half the size of a the rectangle centered. Inside the circle is a check mark.
