Add two-factor authentication and flexible security policies to Atlassian Cloud SSO logins with Duo Single-Sign On, our cloud-hosted SAML 2.0 identity provider, complete with inline self-service enrollment and Duo Prompt.
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.
Duo Single Sign-On, now in public beta, is our cloud-hosted SSO product which 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 Single Sign-On acts as an identity provider (IdP), authenticating your users using existing on-premises Active Directory (AD) or any SAML 2.0 IdP and prompting for two-factor authentication before permitting access to Atlassian Cloud.
Duo Single Sign-On's public beta is available in Duo Beyond, Duo Access, and Duo MFA 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.
Before configuring Atlassian Cloud you'll first need to configure Duo Single Sign-On with a working an authentication source.
Log on to the Duo Admin Panel and navigate to Applications.
Click Protect an Application and locate the entry for Atlassian Cloud with a protection type of "2FA with SSO hosted by Duo (Single Sign-On)" in the applications list. Click Protect to the far-right to start configuring Atlassian Cloud. See Protecting Applications for more information about protecting applications in Duo and additional application options. You'll need the information on the Atlassian Cloud page under Metadata later.
Leave this page open as you'll need this information later.
Add Duo Single Sign-On as a new single sign-on provider for Atlassian Cloud.
While logged into Atlasssian Cloud as an administrator click on Security in the left-hand navigation and then click SAML single sign-on.
On the "SAML single sign-on" page click Add SAML configuration. A new page will appear.
Copy the Identity Provider Entity ID from the Duo Admin Panel Metadata section and paste it into the Atlassian Cloud Identity provider Entity ID field.
Copy the Identity Provider Issuer information from the Duo Admin Panel Metadata section and paste it into the Atlassian Cloud Identity provider SSO URL field.
Click Download certificate next to "Public Certificate" on the Duo Admin Panel under Downloads to download the Duo Single Sign-On signing certificate. Open the certificate file in a text editor (like Notepad), and copy the entire contents of the file (including the
-----BEGIN CERTIFICATE----- and
-----END CERTIFICATE----- lines). Paste the certificate file text into the Public x509 certificate field in Atlassian Cloud.
Click Save configuration. You’ll be returned to the “SAML single sign-on” page with more options.
Locate SP Entity ID and copy everything after https://auth.atlassian.com/saml. If your SP Entity ID was “https://auth.atlassian.com/saml/a12345b6-cd78-9ef0-ghij-k1l234567890” you would copy “a12345b6-cd78-9ef0-ghij-k1l234567890”. You'll need this information later.

Return to the Duo Admin Panel page with the Atlassian Cloud application open.
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 https://yourdomain.atlassian.net then enter yourdomain.
Enter the data you copied earlier from the Atlassian Cloud "SP Entity ID" into the Account Number field.
Atlassian Cloud uses the Mail attribute, Username attribute, First name attribute, and Last name attribute when authenticating. We've mapped the bridge attributes to Duo Single Sign-On supported authentication source attributes as follows:
|Bridge Attribute||Active Directory||SAML IdP|
If you are using non-standard attributes for your authentication source, check the Custom attributes box and enter the name of the attributes you wish to use instead.
You can adjust additional settings for your new SAML application at this time — like changing the application's name from the default value, enabling self-service, or assigning a group policy.
Scroll to the bottom of the page and click the Save button.
You can 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 Single Sign-On login page. Enter your primary directory logon information, approve Duo two-factor authentication, and get redirected back to the Atlassian Cloud site after authenticating.
Congratulations! Your Atlassian Cloud users now authenticate using Duo Single Sign-On.
To minimize additional Duo two-factor prompts when switching between Atlassian Cloud and your other Duo Single Sign-On SAML applications, be sure to apply a shared "Remembered Devices" policy to your SAML applications.
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.
