About this icon
Use the Key icon
Icons in the outline style — like Key — are designed for app navigation bars, toolbar buttons, form labels, and UI controls where clarity at 16–24px is critical. Use it across login and authentication flows, permission management panels, privacy settings, VPN apps, and security dashboards for a consistent, professional look.
IconStash's editor lets you fine-tune color, size, and stroke width in real time, then export in the format that fits your workflow: SVG, PNG, JSX, or CSS background-mask.
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 icon stays pixel-perfect at 16px, 24px, 48px, and any large marketing size.
Design & UX integration
Aesthetic characteristics
Phosphor draws Key with a uniform stroke weight and generous curves. Its defining feature is a six-weight system — Thin, Light, Regular, Bold, Fill and Duotone — so one concept can carry an entire visual hierarchy without you switching icon families mid-product.
UX best practices
Security icons carry more weight than most: users read a lock, shield or key as a trust signal, so the Key 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 — Phosphor
npm install phosphor-react
import { Key } from 'phosphor-react';
// JSX usage:
<Key size={24} weight="regular" />Copy the SVG markup directly from the IconStash editor to use the Key icon without any npm package — paste it into HTML, JSX, or a design tool.
