FAQ
Frequently asked questions
What the Lock icon means and where it's used, then how to install, style, label and license it.
The lock icon represents security or protection, commonly used in user interfaces to denote a secure connection or protected content. It originates from the Octicons library, designed for GitHub. This icon signifies safety and confidentiality.
In software and digital platforms, the lock icon appears in applications like secure login systems, encrypted communication tools, and protected data storage. For example, in a web browser, a lock icon might indicate a secure HTTPS connection.
From a UX perspective, the lock icon communicates trust and security. It helps users understand that their information is protected and that the interface is secure. This icon aids in creating a sense of confidence and safety.
Lock is one of 901 icons in Octicons, made by GitHub and released under MIT. It is drawn on a 12 × 16 grid.
Sign in (it's free), then open Get icon, Install with shadcn CLI, and pick your package manager to copy the command. It adds LockIcon to components/icons/octicon-lock.tsx: one file, a size prop (24 by default) and every SVG prop, with no icon package.
Copy it as React (from Get icon, or the Code section): a typed LockIcon component you paste into your project, with no package to install. Only the icons you import reach your bundle. It works in Next.js and any React app.
Open Get icon, then Copy as code, and pick Vue, Svelte, Angular, Solid or Preact; the Code section shows each one too. Every version is one self-contained component with the SVG inside, and SVG and data URL copies are there for plain HTML and CSS.
With Pro, the shadcn.io MCP server lets Claude Code, Cursor or any MCP client find the Lock icon, or any of 901 Octicons icons, and install it from a prompt.
It's drawn in currentColor, so it takes the text color wherever you use it: a class like text-primary recolors it. To bake a color in, set one in Customize before you copy.
Set width and height on the component, or a class like size-6. It's drawn on a 12 × 16 grid, so it stays sharp at any size. Customize also sets the size it exports at, its padding and rotation.
Yes. It follows the text color, so with text-foreground (or any theme token) it changes with your light and dark themes. The icon is a vector, so it needs no separate dark asset.
Next to a visible label it's decoration: add aria-hidden="true" so screen readers skip it. Standing alone, as in an icon button, give the button a name instead, like aria-label="Lock", so screen readers say what it does.
Yes. LockIcon passes every SVG prop to the svg element, so <LockIcon aria-hidden="true" /> works, and so do role="img" with aria-label, or a title child, when it carries meaning on its own.
Yes. Open Get icon, then Download file: SVG for code or design tools like Figma; PNG, WebP or JPEG at 512px; or an ICO favicon with 16, 32 and 48px inside. Each one uses what you set in Customize.
Yes. MIT allows commercial use; keep the license notice when you ship the icons' source files. The full terms are in the license, linked on this page.
No visible credit is required: MIT only asks that you keep the license notice if you ship the icons' source files. Icons installed with the shadcn CLI already start with a comment naming Octicons, GitHub and the license.
Yes. Copying and downloading it is free, and the shadcn CLI install only needs a free account.
