About the Padlock black outline icon
A closed padlock sits centered in a thin circular frame, with a tall rounded shackle locked into a wide body and a classic keyhole made of a circle over a short slot. The round enclosure gives it a button-like feel, fitting login screens, password fields, security settings panels, checkout pages that signal a safe payment and privacy policy sections.
The body is a broad rectangle with softly rounded corners that balances the narrower arch above it, and the keyhole sits slightly above the vertical center for better optical balance. It pairs with key, shield and unlocked padlock icons in the same security set. Readable down to 20 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.
