The Bandwidth Multi-Factor Authentication API allows developers to generate and verify secure MFA codes delivered via voice calls or SMS messages. It leverages Bandwidth's Voice and Messaging APIs under the hood, handling token generation and management automatically. Developers can customize the code length, expiration time, and delivery message template. The API supports both one-time passcode delivery and verification in a simple two-step workflow.
