Implementing Face ID & Touch ID Authentication in Your Android WebView App: Secure Access Made Easy

In today’s mobile-driven world, security and ease of use go hand-in-hand. Users expect secure yet convenient authentication methods, and leveraging biometric authentication such as Face ID and Touch ID offers both user-friendliness and enhanced security. If you’re developing an Android WebView app, integrating biometric authentication can significantly upgrade your app’s user experience. Here’s how to seamlessly implement Face ID and Touch ID authentication into your Android WebView app.

Why Implement Face ID & Touch ID Authentication?

Biometric authentication has rapidly grown in popularity due to its reliability, convenience, and security. Utilizing Face ID and Touch ID significantly simplifies the authentication process for users, removing the need to enter complex passwords or pins repeatedly. Additionally, biometric data is unique to each individual user, making it inherently more secure and reducing the risks of unauthorized access.

How biometric authentication works on Android

Android developers use the BiometricPrompt API provided by Google to integrate biometric authentication into their apps. Though commonly known as Face ID and Touch ID, these labels typically reference Apple’s implementation; on Android systems, they are simply referred to as facial and fingerprint recognition. Still, the concept and functionality remain consistent: Users authenticate through fingerprint or face scan, and upon successful verification, they gain seamless access to secured app features.

Implementing biometric authentication into your Android WebView App

Follow these straightforward steps to implement biometric authentication into your Android WebView app:

1. Add Biometric Library Dependency:

   implementation 'androidx.biometric:biometric:1.1.0'

2. Configure Manifest Permissions:

   <uses-permission android:name=android.permission.USE_BIOMETRIC />

3. Create Biometric Prompt:

   private void authenticateUser() {
     BiometricPrompt.PromptInfo promptInfo =
         new BiometricPrompt.PromptInfo.Builder()
             .setTitle(Authenticate)
             .setSubtitle(Log in using your fingerprint or face recognition)
             .setNegativeButtonText(Cancel)
             .build();
   
     BiometricPrompt biometricPrompt = new BiometricPrompt(this,
         ContextCompat.getMainExecutor(this),
         new BiometricPrompt.AuthenticationCallback() {
           @Override
           public void onAuthenticationSucceeded(BiometricPrompt.AuthenticationResult result) {
               super.onAuthenticationSucceeded(result);
               loadSecureContent();
           }
         });
   
     biometricPrompt.authenticate(promptInfo);
   }

4. Handle Authentication Results:

   Manage user access based on authentication results by loading secured content within your WebView upon successful verification.

WebView Integration: Secure Your Web Content Easily

When integrating biometric authentication with your WebView app, it’s essential to make sure users only access protected web content after successful authentication. A smooth approach is to trigger the biometric prompt when the application launches or when attempting access to designated protected pages within your WebView.
