Application developers and organizations are increasingly implementing multi-factor authentication to add an extra layer of security to their applications.

In this guide, we'll show you how to add multi-factor authentication to your app with Okta.

Okta gives you the flexibility to deploy our built-in factors, or integrate with existing tokens. Native factors include SMS, and the Okta Verify app for iOS and Android. Integrations include Google Authenticator, RSA SecurID, Symantec VIP, and Duo Security.

Prerequisites

To follow along with this guide, you will need to have your own Okta Developer Edition org and have Postman configured to make API requests to that account.

  1. Creating your Okta Developer Edition org If you don't already have one, create your own Okta Developer Edition org by visiting: https://developer.okta.com/signup/ and following the instructions.
  2. Setting up the Postman API client After you have logged in to your account in your Okta Developer Edition org, follow the instructions on the Okta Developer Documentation page for setting up Postman.

Overview of API calls used for multi-factor authentication

Below is an introduction to using Okta's Multi-Factor Authentication (MFA) API to add MFA to an existing application.

In this guide, you will learn the actual HTTPS requests that are involved in adding MFA to your application. How use actually make these calls will depend on the programming language and web framework that your application uses.

If you are writing code in .NET or Java, Okta has helper libraries that will make it easy to add support for Okta to your application in an idiomatic way.
