What is Verify Silent Network Auth (SNA)?

Silent Network Auth (SNA) is the next generation SIM-based authentication method that confirms phone number possession in real-time without compromising security. Authenticate real, unique end-users without impacting the customer experience. Read What is Silent Network Authentication? on the Twilio Blog for more information on how it works under the hood.

SNA is now available natively through the Verify API.

Start building

1. Request access to the API and Live Test Number feature.

2. Complete the carrier registration form to start the 2-4 week approval process.

3. Plan your implementation starting with the Technical Overview and Verifications API Reference documentation.
