What this category covers
The security category collects icons for lock, shield, key and fingerprint icons for auth flows, permissions and trust badges. Because IconStash indexes 28 libraries side by side, a single search here returns the same concept drawn by many different design teams — which is the fastest way to find an icon that matches your product's existing visual language.
Every result links to a page with the full SVG source, a live preview you can recolour and resize, PNG export at six sizes, and a ready-to-paste React snippet. Nothing is locked behind an account, and the icons come from libraries you can install directly from npm.
What are security icons?
Security icons cover lock, shield, key and fingerprint icons for auth flows, permissions and trust badges. IconStash indexes 3,086 pages in this category across 28 icon libraries, so you can compare how different sets draw the same concept before committing to one.
Which icon library has the best security icons?
It depends on the look you want. By count, the strongest coverage on IconStash comes from Fluent UI Icons (601 matching pages), Material Design Icons (430 matching pages), Material Symbols (307 matching pages). For a minimal, consistent outline set, Lucide is the usual default; for multiple weights from one library, Phosphor gives you six.
Can I download security icons as PNG?
Yes. Every icon in this category can be exported as PNG at 16, 32, 64, 128, 256, or 512 pixels, generated client-side from the original vector. You can also copy the raw SVG, export a React component, or build an SVG sprite.
Are these security icons free for commercial use?
The libraries indexed here are MIT, Apache 2.0, CC BY 4.0, or CC0 licensed, all of which permit commercial use. CC BY sets — such as Solar Icons — require attribution, so check the license shown on each icon page if you cannot provide credit.
How do I pick the right security icon?
Start from recognition rather than style. Choose the glyph your users already associate with the action, then pick the library whose weight matches your interface — lighter sets like Remix Icon suit dense UI, heavier sets like Solar suit marketing and empty states.
