Outline padlock with a semicircular shackle closed over a rectangular body and a centered keyhole
About the Padlock black outline icon
A closed padlock drawn in outline: a wide rounded body, a tall semicircular shackle rising above it, and a centered keyhole formed by a circle over a tapered slot. It reads instantly as locked, private or protected. Use it on login and password fields, checkout pages, privacy settings, VPN dashboards and secure-document slides.
The shackle is an even-weight arc that sits flush on a body roughly twice as wide as it is tall, so the keyhole stays legible at 16 px. Pair it with the open lock, key and shield icons for a full security set.
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.
