Lock Hierarchy

The lock-hierarchy icon represents a secure lock mechanism within a hierarchical structure, often used to signify protection and safety in complex digital systems. This icon is crucial in conveying trust and security, especially in applications dealing with sensitive information in a structured environment. Its design typically features a stylized lock integrated into a hierarchical representation.

The lock-hierarchy icon is commonly found in software and websites that manage access control, such as identity and access management systems, organizational security platforms, or hierarchical databases. For instance, it might appear on a company's security dashboard, an access control panel, or a database management interface.

From a UX perspective, the lock-hierarchy icon communicates a sense of structured security and trust, helping users understand the organization and protection of sensitive information. It often accompanies actions like accessing restricted content, managing user permissions, or configuring security settings.

Lock Hierarchy is one of 1,999 icons in Ultimate free icons, made by Streamline and released under CC BY 4.0. It is drawn on a 24 × 24 grid with a 1.5 stroke.

Sign in (it's free), then open Get icon, Install with shadcn CLI, and pick your package manager to copy the command. It adds LockHierarchyIcon to components/icons/streamline-ultimate-lock-hierarchy.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 LockHierarchyIcon 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 Hierarchy icon, or any of 1,999 Ultimate 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 24 × 24 grid, so it stays sharp at any size. Customize also sets the size it exports at, its padding and rotation, and its stroke.

Lock Hierarchy is a line icon drawn with a stroke width of 1.5. Change it in Customize before you copy, or pass strokeWidth to the installed component when all of its strokes share one width.

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 Hierarchy", so screen readers say what it does.

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