(.NET Core C#) Duo Auth API - Preauth

See more Duo Auth MFA Examples

The /preauth endpoint determines whether a user is authorized to log in, and (if so) returns the user's available authentication factors.

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

For more information, see https://duo.com/docs/authapi#/preauth

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

// generate and send the HMAC signature for the requires based on the integration key and secret key.
