About this icon

Use the Key Fill icon

The Key Fill icon from Phosphor fits naturally in login and authentication flows, permission management panels, privacy settings, VPN apps, and security dashboards. Its bold style makes it ideal for interface components and product UI.

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 Fill icon stays pixel-perfect at 16px, 24px, 48px, and any large marketing size.

Design & UX integration

Aesthetic characteristics

Phosphor draws Key Fill 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 Fill 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 { KeyFill } from 'phosphor-react';

// JSX usage:
<KeyFill size={24} weight="regular" />

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