This package provides a Swift implementation of the WebAuthn API focused on making it
easy to leverage the power of WebAuthn to support Passkeys and security keys.

and WebAuthn dependency to your target:

.target(name: "MyApp", dependencies: [.product(name: "WebAuthn", package: "swift-webauthn")])

Setup

Configure your Relying Party with a WebAuthnManager instance:

let webAuthnManager = WebAuthnManager(
    configuration: WebAuthnManager.Configuration(
        relyingPartyID: "example.com",
        relyingPartyName: "My Fancy Web App",
        relyingPartyOrigin: "https://example.com"
    )
)

  • WebAuthnManager.beginRegistration()
  • WebAuthnManager.finishRegistration()

Authentication
