Locked 1

The locked 1 icon represents a secured or locked state, often used in digital systems to indicate secure connections or authentication. It originates from the concept of physical locks and keys. The locked 1 icon is significant in cybersecurity as it helps users understand the level of security and protection.

In software and platforms, the locked 1 icon appears in applications like banking and finance websites, e-commerce platforms, and secure messaging apps, where users need to authenticate or ensure secure connections. It is also used in password managers like LastPass and 1Password.

From a UX perspective, the locked 1 icon communicates security and trust, helping users feel confident in sharing sensitive information. It facilitates secure interactions and transactions.

Locked 1 is one of 962 icons in Lineicons, made by Lineicons and released under MIT. It is drawn on a 24 × 24 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 Locked1Icon to components/icons/lineicons-locked-1.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 Locked1Icon 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 Locked 1 icon, or any of 962 Lineicons 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.

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="Locked 1", so screen readers say what it does.

Yes. Locked1Icon passes every SVG prop to the svg element, so <Locked1Icon 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 Lineicons, Lineicons and the license.

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

Its tags are security, safety, protection, authentication, access and encryption. Each tag page lists the icons that carry it from every library, which is the quickest way to find a match for Locked 1 in another set.
