FAQ
Frequently asked questions
What the Shield X icon means and where it's used, then how to install, style, label and license it.
What does the Shield X icon mean?
This icon represents security failures and protection rejections in authentication and validation systems. Combining the shield symbol with an X mark, this icon indicates failed security checks, rejected authentication attempts, and the error states where protection mechanisms have denied access or detected security violations requiring attention.
Where is the Shield X icon used?
In authentication failure notifications and security scan results showing threats, users see this icon indicating security check failures and protection denials. Login interfaces display it for failed authentication attempts, while security validation systems use it to indicate rejected access requests or failed security verifications requiring corrective action.
What does the Shield X icon tell users?
The X overlay communicates more than simple failures - it specifically represents security-related rejections, protection denials, and the explicit negative results from security checks and authentication attempts. This symbol emphasizes security enforcement through denial rather than passive failures.
Which library is the Shield X icon from?
Shield X is one of 1,655 icons in Lucide, made by Lucide Contributors and released under ISC. It is drawn on a 24 × 24 grid with a 2 stroke.
How do I install the Shield X icon with the shadcn CLI?
Sign in (it's free), then open Get icon, Install with shadcn CLI, and pick your package manager to copy the command. It adds ShieldXIcon to components/icons/lucide-shield-x.tsx: one file, a size prop (24 by default) and every SVG prop, with no icon package.
How do I use the Shield X icon in Next.js or React?
Copy it as React (from Get icon, or the Code section): a typed ShieldXIcon 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.
Can I import the Shield X icon from lucide-react instead?
Yes, if your project has lucide-react: Shield X is `ShieldXIcon` there, used as <ShieldXIcon />. The shadcn.io MCP server answers with that import when it finds the package. Without it, copy the icon from here.
How do I use the Shield X icon in Vue, Svelte or Angular?
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.
Can my AI agent install the Shield X icon for me?
With Pro, the shadcn.io MCP server lets Claude Code, Cursor or any MCP client find the Shield X icon, or any of 1,655 Lucide icons, and install it from a prompt.
How do I change the color of the Shield X icon?
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.
How do I change the size of the Shield X icon?
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.
How do I change the stroke width of the Shield X icon?
Shield X is a line icon drawn with a stroke width of 2. Change it in Customize before you copy, or pass strokeWidth to the installed component when all of its strokes share one width.
Does the Shield X icon work in dark mode?
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.
How do I make the Shield X icon accessible?
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="Shield X", so screen readers say what it does.
Can I pass aria-hidden or aria-label to the Shield X icon?
Yes. ShieldXIcon passes every SVG prop to the svg element, so <ShieldXIcon aria-hidden="true" /> works, and so do role="img" with aria-label, or a title child, when it carries meaning on its own.
Can I download the Shield X icon as SVG or PNG?
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.
Can I use the Shield X icon in commercial projects?
Yes. ISC 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.
Do I have to credit the author of the Shield X icon?
No visible credit is required: ISC 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 Lucide, Lucide Contributors and the license.
Is the Shield X icon free?
Yes. Copying and downloading it is free, and the shadcn CLI install only needs a free account.
Which other libraries have the Shield X icon?
