Duo Protection for Atlassian Cloud with Duo Access Gateway

Last Updated: February 15th, 2022

Duo offers a variety of methods for adding two-factor authentication and flexible security policies to Atlassian Cloud SSO logins, complete with inline self-service enrollment and Duo Prompt.

Duo Access Gateway reaches 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. Customers may not create new DAG applications after May 19, 2022. Please see the Guide to Duo Access Gateway end of life for more details.

Use the Duo Single Sign-on for Atlassian Cloud application to protect Atlassian Cloud with Duo Single Sign-On, our cloud-hosted identity provider featuring Duo Central and the Duo Universal Prompt.

Protecting Atlassian Cloud requires a subscription to Atlassian Access. Create and configure an Atlassian Access account before continuing.


As business applications move from on-premises to cloud hosted solutions, users experience password fatigue due to disparate logons for different applications. Single sign-on (SSO) technologies seek to unify identities across systems and reduce the number of different credentials a user has to remember or input to gain access to resources.

While SSO is convenient for users, it presents new security challenges. If a user's primary password is compromised, attackers may be able to gain access to multiple resources. In addition, as sensitive information makes its way to cloud-hosted services it is even more important to secure access by implementing two-factor authentication and zero-trust policies.

Duo Access Gateway

Duo Access Gateway (DAG), our on-premises SSO product, layers Duo's strong authentication and flexible policy engine on top of Atlassian Cloud logins using the Security Assertion Markup Language (SAML) 2.0 authentication standard. Duo Access Gateway acts as an identity provider (IdP), authenticating your users using existing on-premises or cloud-based directory credentials and prompting for two-factor authentication before permitting access to Atlassian Cloud.

Duo Access Gateway is included in the Duo Premier, Duo Advantage, and Duo Essentials plans, which also include the ability to define policies that enforce unique controls for each individual SSO application. For example, you can require that Salesforce users complete two-factor authentication at every login, but only once every seven days when accessing Atlassian Cloud. Duo checks the user, device, and network against an application's policy before allowing access to the application.

Deploy or Update Duo Access Gateway

  1. Install Duo Access Gateway on a server in your DMZ. Follow our instructions for deploying the server, configuring DAG settings, and adding your primary authentication source.

  2. Add the attributes from the table below that correspond to the Duo attributes Mail attribute, Username attribute, Last name attribute, and First name attribute in the "Attributes" field when configuring your Active Directory or OpenLDAP authentication source in the DAG admin console, separated by a comma. For example, if Active Directory is your authentication source, enter mail,sAMAccountName,sn,givenName in the "Attributes" field.

    Duo Attribute Active Directory OpenLDAP
    Mail attribute mail mail
    First name attribute givenName gn
    Last name attribute sn sn
    Username attribute sAMAccountName uid

    If your organization uses other directory attributes than the ones listed here then enter those attribute names instead. If you've already configured the attributes list for another cloud service provider, append the additional attributes not already present to the list, separated by a comma.

  3. After completing the initial DAG configuration steps, click Applications on the left side of the Duo Access Gateway admin console.

  4. Scroll down the Applications page to the Metadata section. This is the information you need to provide to Atlassian Cloud when configuring SSO. Click the Download Certificate link to obtain the token signing certificate (the downloaded file is named "dag.crt").

  3. Enter the subdomain used when logging into your company’s Atlassian Cloud account as the Atlassian Cloud Subdomain. For example, if your Atlassian Cloud login URL is then enter yourdomain.

  4. Enter the data you copied earlier from the Atlassian Cloud "SP Entity ID" into the Atlassian Cloud Account Number.

  5. Optional: If you'd like to hide the Atlassian Cloud tile that will take you to the Atlassian Cloud homepage from the Duo Access Gateway Launcher page and add your own links, check the box next to Hide Atlassian Cloud Launcher Tile. You can read more about adding Atlassian Cloud bookmarks later in this page.

  6. Atlassian Cloud uses the Mail attribute, Username attribute, First name attribute, and Last name attribute when authenticating. We've mapped those to DAG supported authentication source attributes as follows:

    Duo Attribute Active Directory OpenLDAP SAML IdP Google Azure
    Mail attribute mail mail mail email mail
    Username attribute sAMAccountName uid sAMAccountName mail mail
    First name attribute givenName gn givenName given_name givenName
    Last name attribute sn sn sn family_name surname

    If you are using non-standard attributes for your authentication source, check the Custom attributes box and enter the names of the attributes you wish to use instead.

  7. Click Save Configuration to generate a downloadable configuration file.

Verify SSO

If your organization enabled the Duo Access Gateway portal, log into the portal page using the link provided by your administrator. Click Atlassian Cloud or the bookmarks you added earlier from the dashboard to access the application.

You can also log on to Atlassian Cloud by going to the URLs of any of your Atlassian Cloud services, typing in your e-mail address, and clicking Continue. This redirects you to the Duo Access Gateway login page. Enter your primary directory logon information, approve Duo two-factor authentication, and get redirected back to the Atlassian Cloud site after authenticating.

DAG Login and Authentication Prompt

Congratulations! Your Atlassian Cloud users now authenticate using Duo Access Gateway.

Configure Allowed Hostnames

If you plan to permit use of WebAuthn authentication methods (security keys, U2F tokens, or Touch ID) in the traditional Duo Prompt, Duo recommends configuring allowed hostnames for this application and any others that show the inline Duo Prompt before onboarding your end-users.

The Duo Universal Prompt has built-in protection from unauthorized domains so this setting does not apply.

Microsoft AD FS

Microsoft's Active Directory Federation Services (AD FS) is a popular choice for SSO because it easily integrates with the AD identity store many organizations already have deployed. Duo's support for cloud applications and SSO drops in to an existing AD FS installation to provide secondary authentication after a user passes primary authentication (successful Active Directory logon).

If you don't already have AD federation running the first step is to install and configure Microsoft AD FS in your organization. Deployment Guides for AD FS versions 2.1, and 3.0/4.0 are available from Microsoft.

Once your AD FS services are up and running, the second step is to configure the SSO partnership between your AD FS service and the external cloud resource, in this case Atlassian Cloud. Learn more about configuring Atlassian Cloud SSO with AD FS at the Atlassian Cloud Support site.

After you have successfully configured and tested AD FS SSO login to Atlassian Cloud using your AD domain credentials, you can then install the Duo AD FS integration. AD FS protection is included with Duo's paid plans.

With the Duo integration for AD FS installed, users pass primary authentication to the AD FS service as usual. Once primary authentication succeeds, users are forwarded to the Duo service for secondary authentication. After approving logon using one of Duo's authentication methods, the user is fully logged in to Atlassian Cloud.
