Duo Single Sign-On for Grafana Cloud

About Duo Single Sign-On

Duo Single Sign-On is our cloud-hosted SSO product which layers Duo's strong authentication and flexible policy engine on top of Grafana Cloud logins using the Security Assertion Markup Language (SAML) 2.0 or OpenID Connect (OIDC) authentication standards. Duo Single Sign-On acts as an OpenID provider (OP), 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 Grafana Cloud.

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 Grafana Cloud. Duo checks the user, device, and network against an application's policy before allowing access to the application.

Configure Single Sign-On

Before configuring Grafana Cloud with Duo SSO using OpenID Connect (OIDC) 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 Grafana Cloud application in Duo.

When configuring an application to be protected with Duo Single Sign-On you'll need to send attributes from Duo Single Sign-On to the application. Active Directory will work with no additional setup, but if you used a SAML idenity provider as your authentication source please verify that you configured it to send the correct SAML attributes.

Below you can see the default bridge attributes that automatically map certain attributes from your authentication source.

Bridge Attribute	Active Directory	SAML IdP
<Username>	sAMAccountName	Username
<Email Address>	mail	Email
<Display Name>	displayName	DisplayName
<First Name>	givenName	FirstName
<Last Name>	sn	LastName

Create the Grafana Cloud Application in Duo

1. Log on to the Duo Admin Panel and navigate to Applications.

2. Click Protect an Application and locate the entry for Grafana 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 Grafana Cloud. See Protecting Applications for more information about protecting applications in Duo and additional application options. You'll need the information on the Grafana Cloud page under Metadata later.

3. The Metadata section contains OpenID provider information about Duo Single Sign-On you will provide to Grafana Cloud at a later configuration step.

4. Scopes are used by Grafana Cloud during authentication to authorize access to a user's details. Each scope returns a set of user attributes (claims) that must be mapped to IdP attributes. When an application sends an OIDC request to Duo SSO, the response sends only the claims from the requested scopes.

   We've automatically enabled the following scopes and mapped the listed attributes. You can change the attribute sent from your authentication source by modifying the IdP Attribute name related to each claim:

   • Profile Scope:

     IdP Attribute	Claim
     <Display Name>	name

   • Email Scope:

     IdP Attribute	Claim
     <Email Address>	email

   • Groups Scope:

     IdP Attribute	Claim
     groups	groups

   

5. You can adjust additional settings for your new SSO application at this time — like changing the application's name from the default value, enabling self-service, or assigning a group policy.

6. Keep the Duo Admin Panel tab open. You will come back to it later.

Duo Universal Prompt

The Duo 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 Grafana Cloud 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. If you created your Grafana Cloud application before March 2024, you can activate the Universal Prompt experience for users from the Duo Admin Panel. Grafana Cloud applications created after March 2024 have the Universal Prompt activated by default.

If you created your Grafana Cloud application before March 2024, 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, before you activate the Universal Prompt for your application.

Activate Universal Prompt

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 "Ready to activate", with these activation control options:

• Show traditional prompt: Your users experience Duo's traditional prompt via redirect when logging in to this application.
• Show new Universal Prompt: (Default) Your users experience the Universal Prompt via redirect when logging in to this application.

The application's Universal Prompt status shows "Activation 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. However, this will still deliver the Duo prompt via redirect, not in an iframe. Keep in mind that support for the traditional Duo prompt ended for the majority of applications in March 2024.

Universal Update Progress

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. 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.

Using SSO

You can log on to Grafana Cloud SSO by navigating to your Grafana Cloud SSO page e.g., https://yourhostname.grafana.net/login. Click Sign in with (your Display Name) to be redirected to Duo Single Sign-On to begin authentication.

Active Directory Login

With Active Directory as the Duo SSO authentication source, enter the primary username (email address) on the Duo SSO login page and click or tap Next.

Enter the AD primary password and click or tap Log in to continue.

Enable Duo Passwordless to log in to Duo SSO backed by Active Directory authentication without entering a password in the future.

SAML Login

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.

Duo Authentication

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 Grafana Cloud to complete the login process.

* Universal Prompt experience shown.

Grafana Cloud supports SP-initiated authentication only, meaning that you must start your SSO login from that application's sign-in page. You won't be able to add as an application tile in Duo Central for IdP-initiated logins.

Congratulations! Your Grafana Cloud users now authenticate using Duo Single Sign-On.

See the full user login experience, including expired password reset (available for Active Directory authentication sources) in the Duo End User Guide for SSO.

Enforce SSO

You can require that all users sign into Grafana Cloud using Duo Single Sign-On.

1. Log into your Grafana Cloud account as an administrator.

2. Under "Manage your stack", in the "Grafana" box, click Launch. Your Grafana Cloud page opens in a new tab.

3. In the top left corner of the page, click the Open menu icon. The left menu sidebar opens.

4. In the left menu sidebar, navigate to Administration → Authentication. The "Authentication" page opens.

5. Click the Generic OAuth tile. The "Generic OAuth" page opens.

6. Scroll down and click the Auto login toggle switch.

7. Scroll down to the bottom of the page and click Save.

Enable Remembered Devices

To minimize additional Duo two-factor prompts when switching between and your other Duo Single Sign-On SAML applications, be sure to apply a shared "Remembered Devices" policy to your SAML applications.
