Closed padlock with a rounded shackle and a small keyhole
About the Padlock black outline icon
A closed padlock sits square on its base, with a tall semicircular shackle locked into the body and a small keyhole made of a circle and a short stem. It is the standard mark for protected content, so it works on login and password fields, HTTPS and checkout badges, privacy settings, locked file lists and access control diagrams.
The body is a tall rounded rectangle rather than the usual squat block, and the shackle rises nearly as high as the case, giving a slim upright silhouette. Pair it with unlock, key and shield icons for a security set. It stays legible down to 16 px.
This is the black outline version of the padlock icon: even, monoline strokes that stay crisp at small sizes and suit clean, minimal interfaces, wireframes and light backgrounds.
