Function Signature 
@available(iOS 16, *)
public func setPasskeyConfiguration(
    relyingParty: String,
    webAuthnHost: String
) throws
Parameters
  • relyingParty: The relying party identifier for WebAuthn/passkey authentication. This is typically your application’s domain name (e.g., “portalhq.io”)
  • webAuthnHost: The WebAuthn host that will handle passkey operations. This should match your application’s authentication server.
Platform Availability
  • Requires iOS 16.0 or later
  • Uses the native passkey APIs introduced in iOS 16
Notes
  • Must be called before using passkey backup or recovery methods
  • The relying party should match your application’s domain name for security purposes
  • Should be used in conjunction with setPasskeyAuthenticationAnchor for complete setup
Example Usage 
// Basic configuration
do {
    try portal.setPasskeyConfiguration(
        relyingParty: "portalhq.io",
        webAuthnHost: "backup.web.portalhq.io"
    )
} catch {
    print("Error configuring passkey authentication: \(error)")
}

// Complete setup with authentication anchor
if #available(iOS 16, *) {
    do {
        // Configure passkey settings
        try portal.setPasskeyConfiguration(
            relyingParty: "portalhq.io",
            webAuthnHost: "backup.web.portalhq.io"
        )

        // Set the authentication anchor (typically your main window)
        try portal.setPasskeyAuthenticationAnchor(view.window!)

        // Now you can use passkey-based backup/recovery
        try await portal.backupWallet(.Passkey) { status in
            print("Backup status: \(status)")
        }
    } catch {
        print("Error setting up passkey authentication: \(error)")
    }
}
Implementation Flow
  1. Check iOS version compatibility
  2. Configure passkey settings using this method
  3. Set the authentication anchor using setPasskeyAuthenticationAnchor
  4. Use passkey-based backup or recovery methods
Security Considerations
  • The relying party identifier is crucial for security and should match your app’s domain
  • Passkeys provide a secure, phishing-resistant alternative to passwords
  • Each passkey is unique to the combination of user account, relying party, and device
