Lock 1

The lock-1 icon represents a variation of the lock symbol, often used to indicate a specific type of security or protection. It is commonly used in user interfaces to add visual interest and create a distinctive design element.

This icon is often used in software and web development to provide users with a sense of trust and confidence. Applications such as Notion, Figma, and web browsers utilize similar icons to indicate secure connections or protected content.

From a UX perspective, the lock-1 icon communicates a sense of safety and reliability. It helps users feel more confident when interacting with interfaces and can be used to draw attention to security features or functionality.

Lock 1 is one of 590 icons in Marketeq, made by Marketeq and released under MIT. It is drawn on a 50 × 50 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 Lock1Icon to components/icons/marketeq-lock-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 Lock1Icon 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 1 icon, or any of 590 Marketeq icons, and install it from a prompt.

It's multicolor, so it keeps its own colors.

Set width and height on the component, or a class like size-6. It's drawn on a 50 × 50 grid, so it stays sharp at any size. Customize also sets the size it exports at, its padding and rotation.

Yes. It keeps its own colors in light and dark mode, so check it against both backgrounds. 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 1", so screen readers say what it does.

Yes. Lock1Icon passes every SVG prop to the svg element, so <Lock1Icon 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 Marketeq, Marketeq and the license.

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