Maui.Biometric

Nuget package CI/CD License: MIT

Provides a cross-platform implementation of biometric authentication.
Supports iOS, macOS, Android and Windows.

Supported Platforms

Platform Minimum Version Supported
iOS 12.2+
macOS 15+
Android 5.0 (API 21)
Windows 11 and 10 version 1809+ (build 17763)

Usage

  • Add NuGet package to your project:
<PackageReference Include="Oscore.Maui.Biometric" Version="2.0.0" />
  • iOS - Add NSFaceIDUsageDescription to your Info.plist to describe the reason your app uses Face ID. (see Documentation). Otherwise the App will crash when you start a Face ID authentication on iOS 11.3+.
	<key>NSFaceIDUsageDescription</key>
	<string>This app requires Face ID for secure authentication and to provide a personalized experience.</string>
  • Android - Request the permission in AndroidManifest.xml
<uses-permission android:name="android.permission.USE_FINGERPRINT" android:maxSdkVersion="27" />
<uses-permission android:name="android.permission.USE_BIOMETRIC" android:minSdkVersion="28" />
  • Add the following to your MauiProgram.cs CreateMauiApp method:
builder
    .UseMauiApp<App>()
+   .UseBiometricAuthentication()
    .ConfigureFonts(fonts =>
    {
        fonts.AddFont("OpenSans-Regular.ttf", "OpenSansRegular");
        fonts.AddFont("OpenSans-Sed:nammibold.ttf", "OpenSansSemibold");
    });
  • Use through BiometricAuthentication.Current or using IBiometricAuthentication from DI:
if (await BiometricAuthentication.Current.IsAvailableAsync())
{
    var result = await BiometricAuthentication.Current.AuthenticateAsync(
        new AuthenticationRequest(
            title: "Authenticate",
            reason: "Please authenticate to proceed"));
    if (result.IsSuccessful)
    {
        // User authenticated
    }
}

Testing on Simulators

iOS

Controlling the sensor on the iOS Simulator

With the Hardware menu you can

  • Toggle the enrollment status
  • Trigger valid (<kbd>⌘</kbd> <kbd>⌥</kbd> <kbd>M</kbd>) and invalid (<kbd>⌘</kbd> <kbd>⌥</kbd> <kbd>N</kbd>) fingerprint sensor events

Android

  • start the emulator (Android >= 6.0)
  • open the settings app
  • go to Security > Fingerprint, then follow the enrollment instructions
  • when it asks for touch
  • open command prompt
  • telnet 127.0.0.1 <emulator-id> (adb devices prints "emulator-<emulator-id>")
  • finger touch 1
  • finger touch 1

Sending fingerprint sensor events for testing the plugin can be done with the telnet commands, too.

Note for Windows users: You have to enable telnet: Programs and Features > Add Windows Feature > Telnet Client
