About this icon
Use the Lock icon
This fill icon from Material Symbols works well across login and authentication flows, permission management panels, privacy settings, VPN apps, and security dashboards. The fill visual style is specifically suited for interface components and product UI.
Customize it in IconStash: pick a color preset or enter any hex code, set exact dimensions, adjust stroke weight, then copy SVG code or download a PNG — no account needed.
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
Lock belongs to Google's Material Symbols, which replaces static icon files with a variable font. Weight, Fill, Grade and Optical Size are all adjustable axes, so one file covers what used to need five. Optical Size is the most useful: the glyph is subtly redrawn for small sizes rather than just scaled down.
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.
