(Excel) 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.
