Futurae Push Notification is a mobile-based authentication method that delivers push notifications to users' smartphones for approving or denying authentication attempts with a single tap. When an authentication event is triggered, a push notification is sent directly to the registered device. The user can open the authenticator app via the notification or navigate to it directly to approve or deny the request. Key characteristics: - All communication between the Futurae API and the user's device is end-to-end encrypted using cryptographic libraries - Supports additional verification layers such as fingerprint scanning, face ID, or a custom PIN - Provides a complete digital audit log with transaction signing - Complies with PSD2, PCI DSS, and HIPAA requirements - Can be integrated via an SDK into an existing mobile app, or deployed using the standalone Futurae authenticator app
