(PHP Extension) Duo Auth API - Auth

See more Duo Auth MFA Examples

The /auth endpoint performs second-factor authentication for a user by sending a push notification to the user's smartphone app, verifying a passcode, or placing a phone call. It is also used to send the user a new batch of passcodes via SMS.

Note: This example requires Chilkat v9.5.0.89 or greater.

// The version number (9_5_0) should match version of the Chilkat extension used, omitting the micro-version number.
// For example, if using Chilkat v9.5.0.48, then include as shown here:
include("chilkat_9_5_0.php");

// This example assumes the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.
