Closed padlock with a square body, rounded shackle and a keyhole
About the Lock Square Padlock black outline icon
A padlock is shown closed, with a plain square body, a tall semicircular shackle seated on top and a keyhole made of a small circle above a tapered slot. It communicates security, restricted access and privacy, so it works for login and password fields, secure checkout badges, encrypted file labels, permission settings and privacy policy sections in apps or slide decks.
The body is an unusually wide square rather than the common rounded rectangle, and the shackle is nearly as tall as the body, which gives the silhouette a taller, more classic profile. The keyhole sits slightly above center for optical balance. Pair it with unlock, key and shield icons, and keep it at 16px or larger so the keyhole does not fill in.
This is the black outline version of the lock square padlock icon: even, monoline strokes that stay crisp at small sizes and suit clean, minimal interfaces, wireframes and light backgrounds.
