Code Lock black outline icon

About the Code Lock black outline icon

A closed padlock drawn inside a thin circle, its square body carrying a rounded input field filled with four asterisks and a row of short dashes beneath, like a keypad or progress track. The combination reads as a passcode rather than a plain lock, which suits login and signup screens, password managers, two-factor prompts, account security settings and data encryption slides.

The shackle is a clean semicircle centered over a body with softly rounded corners, and the asterisk row sits high so the dashes below balance it. It pairs with key, shield and fingerprint icons. Keep it at 32 px or larger, otherwise the four asterisks merge into a single bar.

This is the black outline version of the code lock icon: even, monoline strokes that stay crisp at small sizes and suit clean, minimal interfaces, wireframes and light backgrounds.
