Closed padlock with rounded shackle and keyhole inside a circular outline frame
About the Padlock Security black outline icon
A closed padlock sits inside a thin circle: a rounded shackle arcs above a squared body, and a keyhole with a short slot is centered on the face. The shut shackle communicates protected access, privacy and encrypted data. Place it on login and checkout screens, SSL and privacy policy pages, password managers, VPN apps and security slide decks.
The circular frame leaves generous space around the lock, so the mark stays balanced next to other badge style icons. Pair it with key, shield and unlocked padlock icons to show state changes, and reuse the same frame diameter across the set for an even rhythm.
This is the black outline version of the padlock security icon: even, monoline strokes that stay crisp at small sizes and suit clean, minimal interfaces, wireframes and light backgrounds.
