Implementing Face ID Authentication in Your iOS WebView App: Boost User Security with Native Bio Authentication API

Today, enhancing user security is more critical than ever. Users demand secure and seamless applications, especially when handling sensitive information. If you’re developing an iOS WebView app, implementing Face ID authentication can significantly enhance user security and satisfaction. In this article, we’ll explore how you can implement native biometric authentication in your WebView-based iOS app.

Why Use Face ID Authentication in Your iOS App

Biometric security solutions like Face ID are popular due to their robust security measures, convenience, and enhanced user experience. Unlike passwords and PINs that users might forget or share, Face ID authenticates users through facial recognition technology, significantly lowering the risk of unauthorized access.

Integrating Face ID into your apps elevates trust, providing an added layer of security that’s both seamless and user-friendly.

The Advantage of Using Native APIs

When creating a WebView-based iOS app, tapping into Apple’s built-in native biometric APIs streamlines the integration process. Apple’s LocalAuthentication framework makes it simple for developers to add biometric authentication features quickly and securely without complicating their development process.

The LocalAuthentication framework provides an efficient way to communicate directly with device hardware, ensuring maximum security and reliability.

How to Implement Face ID Authentication within Your WebView App

Let’s briefly cover how you can integrate Face ID authentication within your WebView application step-by-step:

1. Add LocalAuthentication framework: Open your project in Xcode and include the LocalAuthentication framework.
2. Create a new Swift function for biometric authentication: Define a function like:

   import LocalAuthentication
   
   func authenticateUser(completion: @escaping (Bool, Error?) -> Void) {
       let context = LAContext()
       var authError: NSError?
       let reason = Please authenticate using Face ID
   
       if context.canEvaluatePolicy(.deviceOwnerAuthenticationWithBiometrics, error: &authError) {
           context.evaluatePolicy(.deviceOwnerAuthenticationWithBiometrics, localizedReason: reason) { success, evaluateError in
               DispatchQueue.main.async {
                   completion(success, evaluateError)
               }
           }
       } else {
           DispatchQueue.main.async {
               completion(false, authError)
           }
       }
   }

3. Invoke biometric authentication from within WebView logic: Integrate your authentication call into the WebView controller code to trigger authentication as needed. This ensures that critical sections of your app benefit from biometric protection.

Boost Security and User Experience Simultaneously

Implementing Face ID offers more than just strengthened security; it creates an intuitive authentication method users prefer over traditional methods. Apps providing biometric authentication often receive higher user ratings and reviews, boosting overall app performance and reputation.
