Diagonal door key with a round bow, small ring detail and two-toothed blade
About the Key black filled icon
A classic key runs diagonally across the frame: a large circular bow with a small ring set off-center at the top, a long straight shaft, and a blade with two squared teeth at the lower end. It stands for access, authentication and protection. Use it for login and password screens, API key settings, hotel and property listings, locksmith services and encryption or privacy explainers.
The diagonal placement fills the square canvas edge to edge, giving the key more presence than a horizontal version, and the open bow ring keeps the heavy circle from reading as a solid blob. It pairs with padlock, shield and fingerprint icons. Align it on the diagonal axis when placing it beside upright lock icons.
This is the solid black filled version of the key icon: a bold silhouette that reads clearly at 16-24 px and on dark or busy backgrounds, and prints well in one colour.
