Biometric Service

Interface

interface IBiometricService {
  isAvailable(): Promise<boolean>;
  authenticate(reason: string): Promise<boolean>;
}

Implementations

Web (web.ts)

• Uses window.PublicKeyCredential (WebAuthn) where applicable, or falls back to simulated success/failure in dev mode.
• Note: Full biometric support in standard web browsers is limited to secure contexts and specific hardware.

DWEB (dweb.ts)

• Bridges to the native DWEB biometric plugin.
• Supports FaceID, TouchID, and Android Biometrics.

Mock (mock.ts)

• Always returns true for availability.
• Simulates a 1-second delay and returns true for authentication.
