Prerequisites

Silent Authentication involves coordination between the end-user’s mobile app and your backend service. The mobile app manages the user’s session state and responds to updates from the backend, while the backend initiates the verification process by calling the Vonage Verify API.

The verification flow presented in this use case is asynchronous. A synchronous flow is also available, but this use case focuses on the asynchronous approach.

This course assumes that:

• You have a Vonage account. If not, you can create one for free here.
• You have cURL installed in your system.
