Duo Access Gateway Video Overview

Last Updated: April 18th, 2022

Duo Access Gateway adds two-factor authentication, complete with inline self-service enrollment and Duo Prompt to popular cloud services like Salesforce and Google G Suite using SAML 2.0 federation.

Duo Access Gateway reached Last Day of Support on October 26, 2023 for Duo Essentials, Advantage, and Premier customers. As of that date, Duo Support may only assist with the migration of existing Duo Access Gateway applications to Duo Single Sign-On. Please see the Guide to Duo Access Gateway end of life for more details.

Learn more about Duo Single Sign-On, our cloud-hosted identity provider featuring Duo Central and the Duo Universal Prompt.


Duo Access Gateway secures access to cloud applications with your users’ existing directory credentials (like Microsoft Active Directory or Google Workspace accounts) using the Security Assertion Markup Language (SAML) 2.0 authentication standard. SAML delegates authentication from a service provider to an identity provider, and is used for single sign-on (SSO) solutions.

Protected cloud applications redirect your users to the Duo Access Gateway server on your network. Duo Access Gateway acts as a SAML identity provider (IdP), authenticating your users using your existing primary authentication source for credential verification, and then prompting for two-factor authentication before permitting access to the SAML application.

Follow along as this video series takes you through installing Duo Access Gateway on Windows, configuring authentication and other options, and connecting to a cloud service provider.

Please see the Duo Access Gateway documentation for complete deployment instructions. We've also created instructions for configuring SSO in popular supported cloud apps.
