Outline padlock with rounded shackle and a keyhole in the center of the body
About the Lock black outline icon
A closed padlock stands upright: a squat rectangular body with a small keyhole at its center and a smooth arched shackle rising from the top. It reads instantly as protection, privacy and restricted access. Use it on password fields, HTTPS badges, locked settings, private album toggles, and security sections of dashboards or landing pages.
The body is wider than it is tall, giving the shackle room to arc cleanly, and the keyhole keeps its shape down to 16 px. Pair it with the unlocked variant, a key and a shield from the same set; place it inline beside form labels.
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.
