About this icon

Use the Lock icon

Icons in the bold style — like Lock — are designed for interface components and product UI. 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 Lock icon stays pixel-perfect at 16px, 24px, 48px, and any large marketing size.

Design & UX integration

Aesthetic characteristics

Boxicons gives Lock a slightly chunkier, more rounded treatment than most outline sets, and ships Regular, Solid and Logos variants. The Logos subset — brand marks redrawn to match the UI icons — makes it a practical single-dependency choice for marketing sites.

UX best practices

Security icons carry more weight than most: users read a lock, shield or key as a trust signal, so the Lock 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 — Boxicons

npm install react-icons

import { BxLock } from 'react-icons/bx';

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

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