About this icon

Use the Key 3 Line icon

The Key 3 Line icon from Mingcute fits naturally in login and authentication flows, permission management panels, privacy settings, VPN apps, and security dashboards. Its outline style makes it ideal for app navigation bars, toolbar buttons, form labels, and UI controls where clarity at 16–24px is critical.

Open it in IconStash to set stroke color via presets or a custom hex value, choose an exact pixel size (16–512px), control stroke width (0.1–3px), and preview against dark, light, or checkered backgrounds before downloading.

Export formats

Copy clean SVG vectors with one click, generate custom-size PNG files from 16px to 512px, export JSX/React components ready to paste into your project, or use the icon as a CSS background-mask for flexible theming.

All exports are based on the same editable vector — so the Key 3 Line icon stays pixel-perfect at 16px, 24px, 48px, and any large marketing size.

Design & UX integration

Aesthetic characteristics

MingCute draws Key 3 Line with soft, slightly rounded terminals that read as friendly rather than technical. Most concepts ship in both line and filled versions, which is useful when one icon needs to signal both an inactive and an active state without you sourcing a second set.

UX best practices

Security icons carry more weight than most: users read a lock, shield or key as a trust signal, so the Key 3 Line icon should never be decorative. Place it next to the mechanism it actually describes — the payment step, the HTTPS indicator, the permission toggle — rather than in a generic header where it implies protection that may not exist.

Use in your project

React / npm — Mingcute

npm install @mingcute/icon-react

import { Key3LineLine } from '@mingcute/icon-react';

// JSX usage:
<Key3LineLine size={24} />

Copy the SVG markup directly from the IconStash editor to use the Key 3 Line icon without any npm package — paste it into HTML, JSX, or a design tool.
