About this icon

Use the Shield Lock Outline icon

Icons in the outline style — like Shield Lock Outline — 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 Shield Lock Outline icon stays pixel-perfect at 16px, 24px, 48px, and any large marketing size.

Design & UX integration

Aesthetic characteristics

Shield Lock Outline 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 Shield Lock Outline 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.
