<head> element. The library's methods will be available on the global SimpleWebAuthnBrowser
object.
NOTE: The only difference between the two packages below is that the ES5 bundle includes some polyfills for older browsers. This adds some bundle size overhead, but does enable use of
browserSupportsWebAuthn()in older browsers to show appropriate UI when WebAuthn is unavailable.
ES2021
If you only need to support modern browsers, include the ES2021 version:
<script src="https://unpkg.com/@simplewebauthn/browser/dist/bundle/index.umd.min.js"></script>
ES5
If you need to support WebAuthn feature detection in deprecated browsers like IE11 and Edge Legacy,
include the ES5 version:
<script src="https://unpkg.com/@simplewebauthn/browser/dist/bundle/index.es5.umd.min.js"></script>
