Lock Closed Key 16 Filled

The lock-closed-key-16-filled icon represents a locked state with a key, indicating security and protection. It is commonly used in digital interfaces to signify a secure or private area. This icon is part of the Fluent UI System Icons library, designed by Microsoft Corporation.

In software applications, this icon appears in various contexts, such as login screens, password-protected areas, or secure data storage. For example, it may be used in software applications or digital platforms to indicate a secure section or feature.

From a UX perspective, the lock-closed icon communicates that a certain area or feature is restricted and requires authentication or authorization to access. It helps users understand the functionality and navigate interfaces more effectively.

Lock Closed Key 16 Filled is one of 19,257 icons in Fluent UI System Icons, made by Microsoft Corporation and released under MIT. It is drawn on a 16 × 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 LockClosedKey16FilledIcon to components/icons/fluent-lock-closed-key-16-filled.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 LockClosedKey16FilledIcon 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 Closed Key 16 Filled icon, or any of 19,257 Fluent UI System 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 16 × 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 Closed Key 16 Filled", so screen readers say what it does.

Yes. LockClosedKey16FilledIcon passes every SVG prop to the svg element, so <LockClosedKey16FilledIcon 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 Fluent UI System Icons, Microsoft Corporation and the license.

Yes. Copying and downloading it is free, and the shadcn CLI install only needs a free account.

Its tags are UI, security, grid, mixed, other and privacy. Each tag page lists the icons that carry it from every library, which is the quickest way to find a match for Lock Closed Key 16 Filled in another set.

Fluent UI System Icons draws many icons in several styles: Filled and Regular next to the default. Open the library and pick a style above the grid to see Lock Closed Key 16 Filled's siblings in it.
