IBiometrics
Namespace: BlazorNative.Device
DI-injectable façade over biometric authentication (Face ID / Touch ID /
fingerprint). Inject this rather than the low-level BlazorNative.Core.IMobileBridge;
IBiometrics.AuthenticateAsync(String, CancellationToken) proves who is holding the device and returns a
BlazorNative.Core.BiometricStatus value (failure, cancellation, lockout and no-hardware
are DATA, never an exception), while IBiometrics.IsAvailableAsync(CancellationToken) reports presence
and enrolment without prompting. Register it with
ServiceCollectionExtensions.AddBlazorNativeDevice(IServiceCollection).
public interface IBiometrics
Methods
AuthenticateAsync(String, CancellationToken)
Shows an OS biometric prompt (Face ID / Touch ID / fingerprint) with
reason as its message and returns the terminal
BlazorNative.Core.BiometricStatus — a failure / cancellation / lockout / no-hardware
outcome is DATA, never a throw. Returns no token and no secret: the status is
the whole answer.
ValueTask<BiometricStatus> AuthenticateAsync(string reason, CancellationToken ct = null)
Parameters
reason String
Returns
IsAvailableAsync(CancellationToken)
Reads whether biometric authentication is available (hardware present AND at least one biometric enrolled) WITHOUT prompting — for a UI that wants to show state before offering a biometric action.
ValueTask<bool> IsAvailableAsync(CancellationToken ct = null)
