Key Icon
key · Security · 6 styles
Open the Security set and Key is one of the glyphs you get. It is one of 46 glyphs in that category and one of 1,246 icons in the library overall, each drawn on the same 24x24 grid so Key lines up optically with everything around it. The icon is addressed in templates by the string "key", and every style variant resolves from that single name.
The metaphor here is keys and credentials. That places Key in the Security family, which covers locks, keys, shields and access control and turns up in login screens, permission matrices, 2FA flows and privacy settings. Teams building products where trust has to be visible reach for this set first. Use Key where the label alone would be ambiguous — an icon-only button, a dense table row, a mobile tab bar — and keep an accessible name on the control, because the SVG itself is decorative.
Key in 6 styles
Key ships in 6 style variants: Bold, Bold Duotone, Linear, Outline, Broken and Line Duotone. Bold gives you solid filled shapes that hold their weight at 16px and read clearly against coloured backgrounds. Bold Duotone gives you a filled body with a second, lower-opacity layer that adds depth without a second colour token. Linear gives you even 1.5px strokes, the neutral default for dense interfaces and toolbars. A common pairing is Bold for the selected state and Line Duotone for the rest, so the active item reads without a colour change.

You register only the variants you actually render, so nothing unused reaches the bundle. Import KeyBold from the "@rchernando/solar-icons/security" entry point, hand it to provideSolarIcons in your application config or in a route-level providers array, and render it with the solar-icon component. All 6 exports for key live in that same entry point, so switching style is a one-line change.
import { KeyBold, KeyBoldDuotone, KeyLinear, KeyOutline, KeyBroken, KeyLineDuotone } from '@rchernando/solar-icons/security';import { ApplicationConfig } from '@angular/core';
import { provideSolarIcons } from '@rchernando/solar-icons';
import { KeyBold } from '@rchernando/solar-icons/security';
export const appConfig: ApplicationConfig = {
providers: [provideSolarIcons(KeyBold)]
};<solar-icon name="key" iconStyle="bold" size="24px" />
<solar-icon name="key" iconStyle="bold-duotone" size="24px" />
<solar-icon name="key" iconStyle="linear" size="24px" />
<solar-icon name="key" iconStyle="outline" size="24px" />
<solar-icon name="key" iconStyle="broken" size="24px" />
<solar-icon name="key" iconStyle="line-duotone" size="24px" />More Security icons
Icons drawn alongside it in Security include Eye Scan, Eye, Bomb Minimalistic, Bomb, Siren, Shield User, Shield Star and Shield Network. They share stroke weight and corner radius with Key, so mixing them in one toolbar stays consistent.
Icons related to Key
If Key is not quite the shape you want, Key Minimalistic, Key Minimalistic Square, Key Minimalistic Square2, Key Minimalistic Square3 and Key Minimalistic2 share part of its name and often work as substitutes.
Elsewhere in the library
Across the rest of the set, Align Left, Safe Square, Heart, Bluetooth Square, Sort Horizontal and List Arrow Up Minimalistic cover neighbouring ideas; the name "key" is 3 characters long and splits into 1 token, which is how the explorer's search matches it.
Key icon FAQ
- How do I use the key icon in Angular?
- Import KeyBold from "@rchernando/solar-icons/security", register it with provideSolarIcons(KeyBold) and render <solar-icon name="key" iconStyle="bold" />. No HTTP request is made — the SVG is inlined at build time.
- Which styles does Key support?
- 6 of them: Bold, Bold Duotone, Linear, Outline, Broken and Line Duotone. Each is a separate export, so you only ship the ones you import.
- Can I change the size and colour of key?
- Yes. The size input accepts any CSS length and the SVG uses currentColor, so Key inherits the text colour of its container — a Tailwind class such as text-violet-400 is enough.
