Closed padlock with an arched shackle and a round keyhole on the body
About the Padlock Keyhole black outline icon
A square padlock body carries a circular keyhole with a short vertical slot below it, topped by a tall arched shackle drawn as a double outline. It signals locked state, password protection, encrypted content, private settings and restricted access. Use it on login and sign-up forms, password fields, HTTPS or secure-checkout badges, privacy policy sections and admin permission screens.
The shackle takes nearly half the icon height, giving a tall silhouette that stays recognizable in a browser address bar or a form label. The keyhole is centered and open so it does not clog at small sizes. Pair it with an unlocked variant for toggle states, plus key, shield and fingerprint icons for a full security set.
This is the black outline version of the padlock keyhole icon: even, monoline strokes that stay crisp at small sizes and suit clean, minimal interfaces, wireframes and light backgrounds.
It downloads free as an SVG vector or transparent PNG in seven sizes, and the free online editor lets you recolor it, apply gold, silver, neon and gradient styles, add animation, or convert it to EPS, PDF and DXF.
