How to Integrate Face ID Using WebViewGold‘s Bio Authentication API

Let’s dive into how you can implement Face ID authentication quickly using WebViewGold‘s Bio Authentication API. This guide is concise, straightforward, and easy to follow, even if you’re new to iOS development.

Step 1: Set Up WebViewGold for Your Website

First, ensure your website is successfully integrated into an iOS app using WebViewGold. If this isn’t done yet, it’s easy! Simply configure your website URL in the WebViewGold app template, customize appearance settings, and build your app through Xcode. No complex coding needed.

Step 2: Enable Bio Authentication in WebViewGold Settings

Within the WebViewGold framework, navigate to the configuration file or settings within your Xcode project. Locate the setting labeled Bio Authentication and enable it. This will automatically unlock the capability of using Face ID and Touch ID provided by the WebViewGold Bio Authentication API.

Step 3: Trigger Bio Authentication From JavaScript

Once enabled, you can directly communicate to Bio Authentication from your web app using simple JavaScript commands. WebViewGold exposes JavaScript functionalities that allow your web scripts to trigger biometric authentication seamlessly. Here’s a quick example:

function authenticateUser() {
    window.webkit.messageHandlers.bioAuth.postMessage(authenticate);
}

This short snippet enables your website’s login button or any secured area to initiate Face ID instantly.

Step 4: Handling Authentication Responses

After triggering biometric authentication, WebViewGold will return a response to your website’s JavaScript code so you can manage your app’s logic based upon user authentication success or failure:

window.addEventListener('message', function(event) {
    if (event.data == bioAuthSuccess) {
        // User authenticated successfully via Face ID
        alert(Authentication successful!);
        // Proceed to protected content
    } else if (event.data == bioAuthFailure) {
        // Authentication failed or canceled
        alert(Authentication failed, please try again.);
    }
});

Customizing Authentication Prompts

Thanks to WebViewGold, customizing and localizing Face ID prompts is effortless. Adjust messages in your project’s settings to showcase tailored prompts like Use Face ID to Login, providing a personalized feel.

Testing and Deploying Your App

Before launching, thoroughly test biometric authentication on physical devices since simulators won’t always replicate real-world scenarios accurately. Once satisfied, export and submit your WebViewGold-powered app to Apple’s App Store for review. The process is intuitive, streamlined, and documented clearly within WebViewGold’s comprehensive documentation.
