Key Benefits:

Follow these steps to install and configure the CrossClassify Smart MFA Plugin for your Clerk-powered app:

install `xc-clerk-react` as a dependency:

npm install --save xc-clerk-react

Visit the CrossClassify website and explore the “See how it works”.

Check your email for the API key sent by CrossClassify.

Get `clerk_key` from the Clerk Website by creating a new project.

Setup the environments in the .env file and provide the API-key and clerk-key based on following code:

VITE_CROSS_CLASSIFY_PUBLISHABLE_API_KEY=api_key VITE_CLERK_PUBLISHABLE_KEY=clerk_key

Wrap your React app with the provider:

import { ClerkProvider } from '@clerk/clerk-react' // Import your publishable key const PUBLISHABLE_KEY = import.meta.env.VITE_CLERK_PUBLISHABLE_KEY if (!PUBLISHABLE_KEY) { throw new Error("Missing Publishable Key") } ReactDOM.createRoot(document.getElementById('root')).render( <React.StrictMode> <ClerkProvider publishableKey={PUBLISHABLE_KEY}> <App /> </ClerkProvider> </React.StrictMode>, )

Render your `Signin` and `Signup` pages with this structure

import { SecureSignIn, SecureSignUp } from "xc-clerk-react"; export default function App() { const [showSignUp, setShowSignUp] = useState(false); return ( <div> <SignedIn> {/* The user is signed in, show the main application */} <header> <UserButton /> {/* Rest of your app components */} <h1>Welcome to the app!</h1> </header> </SignedIn> <SignedOut> {/* The user is not signed in, show the sign-in or sign-up form */} {showSignUp ? <SecureSignUp /> : <SecureSignIn />} <button onClick={() => setShowSignUp(!showSignUp)}> {showSignUp ? 'Have an account? Sign In' : 'Need an account? Sign Up'} </button> </SignedOut> </div> ); }
