About the Lock Closed black outline icon
A padlock sits locked inside a thin circular frame: a tall arched shackle seated on a wide rounded body, with a small keyhole made of a circle and a short slot at its center. It communicates security, privacy and restricted access. Use it for login and password fields, secure checkout badges, encrypted file states, privacy settings and locked content markers.
The shackle rises well above the body so the closed state is obvious at a glance, and the enclosing circle lets it work as a standalone badge. Pair it with unlock, key and shield icons for an access set. Keep it at 24 px or larger so the keyhole reads.
This is the black outline version of the lock closed icon: even, monoline strokes that stay crisp at small sizes and suit clean, minimal interfaces, wireframes and light backgrounds.
