About this icon
Use the Lock icon
The Lock icon (Octicons) is categorized under Security. Its outline style is optimal for app navigation bars, toolbar buttons, form labels, and UI controls where clarity at 16–24px is critical and scales cleanly from 16px to 512px.
Use the IconStash detail panel to preview with a custom background, adjust stroke width, and generate production-ready SVG or PNG files without any external tools.
Export formats
Copy clean SVG vectors with one click, generate custom-size PNG files from 16px to 512px, export JSX/React components ready to paste into your project, or use the icon as a CSS background-mask for flexible theming.
All exports are based on the same editable vector — so the Lock icon stays pixel-perfect at 16px, 24px, 48px, and any large marketing size.
Design & UX integration
Aesthetic characteristics
Octicons is GitHub's own icon set, so Lock is tuned for the density of GitHub's interface — small default sizes, tight shapes, and silhouettes that stay identifiable at 16px. That makes it a reliable baseline for developer tooling, code review screens and anything code-adjacent.
UX best practices
Security icons carry more weight than most: users read a lock, shield or key as a trust signal, so the Lock icon should never be decorative. Place it next to the mechanism it actually describes — the payment step, the HTTPS indicator, the permission toggle — rather than in a generic header where it implies protection that may not exist.
Use in your project
React / npm — Octicons
npm install @primer/octicons-react
import { LockIcon } from '@primer/octicons-react';
// JSX usage:
<LockIcon size={24} />Copy the SVG markup directly from the IconStash editor to use the Lock icon without any npm package — paste it into HTML, JSX, or a design tool.
