Idea of Login Rounded Icon
It's a logo of login rounded reduced to an image of an arrow pointed west. The logo is enclosed by a circle that borders it. It reminds me of the back icon on a browser, except a circle is around it.
This Login Rounded icon is made in Material Design style
developed by Google. This style is based on extremely simplified shapes, thin two-pixel lines, and is optimized for 24x24 px. Unlike other vector icon packs that have merely hundreds of icons, this icon pack contains 6,100 icons, all in the same style and quality.
