This is a Closed Topic 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 13,000 icons, all in the same style and quality.
This icon is a circular speech bubble, with a curved point at its bottom coming from the bottom left. Inside the speech bubble is an icon of a lock, which is a small rectangle with a hole in the middle and a curved line on top.
