About this icon
Use the Lock Thin icon
The Lock Thin icon from Phosphor fits naturally in login and authentication flows, permission management panels, privacy settings, VPN apps, and security dashboards. Its thin style makes it ideal for editorial layouts, hero sections, premium marketing pages, and large-format typographic contexts.
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 Lock Thin icon stays pixel-perfect at 16px, 24px, 48px, and any large marketing size.
Design & UX integration
Aesthetic characteristics
Phosphor draws Lock Thin 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 Lock Thin 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 { LockThin } from 'phosphor-react';
// JSX usage:
<LockThin size={24} weight="regular" />Copy the SVG markup directly from the IconStash editor to use the Lock Thin icon without any npm package — paste it into HTML, JSX, or a design tool.
