Interface Essential Lock

The lock icon represents a security or authentication feature, often used to indicate a secure connection or protected area. It is commonly associated with encryption, passwords, and access control.

In software and digital platforms, the lock icon appears in various contexts, such as login pages, password managers, and secure communication apps like Signal or WhatsApp.

From a UX perspective, the lock icon communicates safety and trust, helping users feel confident in sharing sensitive information or accessing protected resources.

Interface Essential Lock is one of 662 icons in Pixel free icons, made by Streamline and released under CC BY 4.0. It is drawn on a 32 × 32 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 InterfaceEssentialLockIcon to components/icons/streamline-pixel-interface-essential-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 InterfaceEssentialLockIcon 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 Interface Essential Lock icon, or any of 662 Pixel free icons 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 32 × 32 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="Interface Essential Lock", so screen readers say what it does.

Yes. InterfaceEssentialLockIcon passes every SVG prop to the svg element, so <InterfaceEssentialLockIcon 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.
