Outline icon of a padlock with a rounded shackle and a keyhole
About the Lock black outline icon
This icon shows a classic padlock: a rounded U-shaped shackle sits above a square body with a keyhole cut into its center. It communicates security, privacy, protection and restricted access. Use it for login screens, password fields, privacy settings, security badges, checkout pages and account menus.
The shackle is drawn as a smooth arch and the keyhole combines a circle with a small trapezoid, giving the padlock a recognizable, legible shape at small sizes. It pairs well with key, shield and fingerprint icons in security UI. Works well as a status icon beside locked settings.
This is the black outline version of the lock icon: even, monoline strokes that stay crisp at small sizes and suit clean, minimal interfaces, wireframes and light backgrounds.
