Add two-factor authentication and flexible security policies to Datadog SAML 2.0 logins with Duo Single-Sign On, our cloud-hosted SSO identity provider, offering inline self-service enrollment and authentication with Duo Universal 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 and zero-trust policies.
Duo Single Sign-On is our cloud-hosted SSO product which layers Duo's strong authentication and flexible policy engine on top of Datadog logins. Duo Single Sign-On acts as an identity provider (IdP), authenticating your users using existing on-premises Active Directory (AD) or another SSO IdP. Duo SSO prompts users for two-factor authentication and performs endpoint assessment and verification before permitting access to Datadog.
Duo Single Sign-On is available in 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 Datadog. Duo checks the user, device, and network against an application's policy before allowing access to the application.
Before configuring Datadog with Duo SSO using Security Assertion Markup Language (SAML) 2.0 authentication you'll first need to enable Duo Single Sign-On for your Duo account and configure a working authentication source.
Once you have your SSO authentication source working, continue to the next step of creating the Datadog application in Duo.
Log on to the Duo Admin Panel and navigate to Applications.
Click Protect an Application and locate the entry for Datadog 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 Datadog. See Protecting Applications for more information about protecting applications in Duo and additional application options. You'll need the information on the Datadog page under Downloads later.
Click Download XML to download the Identity Provider (IdP) Metadata XML file.
Datadog uses the 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.
Keep the Duo Admin Panel tab open. You will come back to it later.
The new Universal Prompt provides a simplified and accessible Duo login experience for web-based applications, offering a redesigned visual interface with security and usability enhancements.
|Universal Prompt||Traditional Prompt|
We've already updated the Duo Datadog application hosted in Duo's service to support the Universal Prompt, so there's no action required on your part to update the application itself. You can activate the Universal Prompt experience for users of new and existing Duo Datadog applications from the Duo Admin Panel.
Before you activate the Universal Prompt for your application, it's a good idea to read the Universal Prompt Update Guide for more information about the update process and the new login experience for users.
Activation of the Universal Prompt is a per-application change. Activating it for one application does not change the login experience for your other Duo applications.
The "Universal Prompt" area of the application details page shows that this application is "New Prompt Ready", with these activation control options:
Enable the Universal Prompt experience by selecting Show new Universal Prompt, and then scrolling to the bottom of the page to click Save.
Once you activate the Universal Prompt, the application's Universal Prompt status shows "Update Complete" here and on the Universal Prompt Update Progress report.
Should you ever want to roll back to the traditional prompt, you can return to this setting and change it back to Show traditional prompt.
Click the See Update Progress link to view the Universal Prompt Update Progress report. This report shows the update availability and migration progress for all your Duo applications in-scope for Universal Prompt support. You can also activate the new prompt experience for multiple supported applications from the report page instead of visiting the individual details pages for each application.
Add Duo Single Sign-On as a new single sign-on provider in Datadog.
Open a new tab in your browser and log on to your Datadog account.
In the menu on the left, hover over your username and click Organization Settings.
Under "SECURITY", click Login Methods.
In the SAML field, click Configure.
At the top of the page, click Choose File.
Navigate to the Identity Provider (IdP) Metadata XML file and upload the XML file you downloaded from the Duo Admin Panel in the previous section.
At the bottom right of the page, click Upload and Enable.
Click the Identity Provider (IdP) Initiated Login checkbox and then click Save Changes.
In the SAML field, set Enabled by Default to On and then click Update.
In the Additional Features section, copy the Assertion Consumer Service URL.
Return to the Duo Admin Panel with the Datadog application open and paste the assertion consumer service URL into the ACS URL field.
Scroll to the bottom of the page and click Save.
Learn more about Datadog SSO at Datadog Docs.
You can log on to Datadog by navigating to your Datadog SSO page e.g., https://app.datadoghq.com/account/login/id/userid. Enter your password and click Log In to be redirected to Duo Single Sign-On to begin authentication.
With Active Directory as the Duo SSO authentication source, enter the primary username (email address) on the Duo SSO login page and click Next.
Enter the AD primary password and click Log in to continue.
With another SAML identity provider as the Duo SSO authentication source, Duo SSO immediately redirects the login attempt to that SAML IdP for primary authentication. Users do not see the Duo SSO primary login screen.
Successful verification of your primary credentials by Active Directory or a SAML IdP redirects back to Duo. Complete Duo two-factor authentication when prompted and then you'll return to Datadog to complete the login process.

You can also log into Datadog using Duo Central, our cloud-hosted portal which allows users to access all of their applications in one spot. Link to Datadog in Duo Central by adding it as an application tile. Once the tile has been added, log into Duo Central and click the tile for Datadog.
Congratulations! Your Datadog users now authenticate using Duo Single Sign-On.
To minimize additional Duo two-factor prompts when switching between Datadog and your other Duo Single Sign-On SAML applications, be sure to apply a shared "Remembered Devices" policy to your SAML applications.
