​
This is only for use with signin. Passkey is not currently supported for registration.

​
Summary

This hook provides a way for clients to sign-in to Dynamic using a passkey. The hook needs to be initialized within a child of DynamicContextProvider.

​
Usage

Available methods:
  • signInWithPasskey: Sign in to Dynamic by calling the function returned from this hook. This will automatically set the logged-in Dynamic user when successful.

​
Usage

import { useSignInWithPasskey } from '@dynamic-labs/sdk-react-core';

const App = () => {
  const signInWithPasskey = useSignInWithPasskey();

  return (
    <button
      onClick={() => signInWithPasskey()}
    >
      Sign in with passkey
    </button>
  );
};

​
Prerequisites

Before using this hook, ensure that:
  1. Passkey Authentication is Enabled as an authentication method.
  2. Domain Configuration: For production use, your domain must be properly configured for WebAuthn. This includes:
    • HTTPS protocol (required for passkeys)
    • Proper domain registration in your Dynamic environment settings
  3. User Has Registered Passkey: The user must have previously registered a passkey with your application. If they haven’t, they’ll need to register one first using the Dynamic widget or appropriate registration flow.
  4. Browser Support: Ensure the user’s browser supports WebAuthn. Most modern browsers support passkeys, but you may want to add feature detection.

​
Important Notes

Domain Scope: Passkeys are scoped to top-level domains. A passkey created on app.example.com will work on example.com and shop.example.com, but will require a new registration for app.different.com.
Browser Compatibility: While most modern browsers support passkeys, always implement fallback authentication methods for broader compatibility.
First-Time Users: Users who haven’t registered a passkey will need to complete the registration process before they can use this sign-in method. Consider providing clear instructions or alternative authentication options.
