Implementing Bio Authentication (Face ID & Touch ID) in Your iOS WebView App: Enhancing User Security with WebViewGold

Today’s mobile applications require robust security measures, especially when handling sensitive user information or transaction-focused use cases. If you have an iOS WebView-based application, integrating biometric authentication such as Face ID or Touch ID not only enhances user experience but also significantly boosts overall security.

Why Bio Authentication Matters for Your iOS WebView App

The modern user expects convenience coupled with security. Biometric authentication offers exactly that—a seamless, fast, and secure method of identity verification. With Face ID and Touch ID, your users no longer need to remember intricate passwords or risk having their credentials compromised. Instead, logging in becomes a breeze, performed securely through their unique biological markers.

By adding biometric authentication, you gain:

• Increased security: Biometrics are significantly harder to forge compared to passwords.
• Improved UX: Users can quickly authenticate without hassle, enhancing their overall app satisfaction.
• Higher engagement rate: With simplified login, users are encouraged to frequently engage with your app.

Implementing Face ID & Touch ID in Your WebView App

Integrating biometric authentication into an existing WebView-based app involves utilizing Apple’s LocalAuthentication framework, available within Xcode. Follow these straightforward steps for quick implementation:

• Step 1: Add the LocalAuthentication Framework
  In your Xcode project, navigate to your project settings—under General, scroll down to Frameworks, Libraries, and Embedded Content, and add LocalAuthentication.framework.
• Step 2: Import the Framework in your ViewController
  At the top of your ViewController Swift file, include:
  import LocalAuthentication
• Step 3: Implement Biometric Authentication Logic
  Within your ViewController, you can verify biometrics availability and authenticate users with this code snippet:

  let context = LAContext()
  var error: NSError?
  
  if context.canEvaluatePolicy(.deviceOwnerAuthenticationWithBiometrics, error: &error) {
      let reason = Authenticate to access your account.
  
      context.evaluatePolicy(.deviceOwnerAuthenticationWithBiometrics, localizedReason: reason) { success, authenticationError in
          DispatchQueue.main.async {
              if success {
                  // Authentication successful. Continue to your app content.
              } else {
                  // Authentication failed. Handle the error accordingly.
              }
          }
      }
  } else {
      // Biometrics unavailable. Fallback to a password or alternate auth.
  }
  

• Step 4: Connect with your existing WebView session logic
  Once biometric authentication succeeds, proceed to load your protected website content within your established WKWebView. This ensures your web-based sessions also benefit from added security.
