# MFA (Multi-Factor Authentication) Overview

## Overview

**MFA**(**Multi-Factor Authentication**) is an extra security method that requires a user to complete two or more forms of authentication prerequisites before logging into an **Application**or website. This method often requires that the user responds to a security question, provides an emailed passcode, etc., in addition to simply providing the correct password on sign-in.

Typically, MFA functionality is provided to an **Application**or website, via a third-party application. To enable this function in Decisions, users may choose their desired MFA, authorize it via their desired IdP(Identity Provider), and then create an integration between Decisions and that IdP.

## 2FA(Two-Factor Authentication)

2FA is included within the Decisions environment, which makes it accessible for users without integration from a third-party application. For more information on 2FA, please refer to [Setting Up 2FA (Two Factor Authentication)](/v9/docs/2fa-two-factor-authentication-in-decisions)

2FA is only meant for use with the login process. It cannot be called from a Flow via API.

## Resources for Third-Party Integration

Although Decisions comes equipped with 2FA, the platform supports integration with other forms of MFA. The following is a non-exhaustive list of documentation relating to integrating with an **IdP**and/or enabling **MFA**. It is recommended that, if the document is not listed, seek out information from the desired IdP on how to enable MFA before integrating with **Decisions**.
