Duo Single Sign-On for Google Chrome Enterprise

Last updated:

Add two-factor authentication and flexible security policies to your Google Chrome Enterprise logins with Duo Single-Sign On. Our cloud-hosted OpenID identity provider offers inline user enrollment, self-service device management, and support for a variety of authentication methods — such as passkeys and security keys, Duo Push, or Verified Duo Push — in the Universal Prompt.

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 Google Chrome Enterprise 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 Google Chrome Enterprise.

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 Google Chrome Enterprise. Duo checks the user, device, and network against an application's policy before allowing access to the application.

Configure Single Sign-On

Before configuring Google Chrome Enterprise with Duo SSO using OpenID Connect (OIDC) authentication you'll first need to configure a working authentication source.

Once you have your SSO authentication source working, continue to the next step of creating the Google Chrome Enterprise 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 identity provider as your authentication source please verify that you configured it to send the correct SAML attributes.

These default attributes automatically map certain attributes from your authentication source.

Default 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 Google Chrome Enterprise Application in Duo

  1. Log in to the Duo Admin Panel and navigate to ApplicationsApplication Catalog.

  2. Locate the entry for Google Chrome Enterprise with the "SSO" label in the catalog. Click the + Add button to start configuring Google Chrome Enterprise. See Protecting Applications for more information about protecting applications with Duo and additional application options. You'll need the information on the Google Chrome Enterprise page under Metadata later.

  3. No users can log in to new applications until you grant access. Update the User access setting to grant access to this application to users in selected Duo groups, or to all users. Learn more about user access to applications. If you do not change this setting now, be sure to update it so that your test user has access before you test your setup.

  4. The Metadata section contains OpenID provider information about Duo Single Sign-On you will provide to Google Chrome Enterprise at a later configuration step.

  5. Scopes are used by Google Chrome Enterprise 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
    Duo Google Chrome Enterprise OIDC Response Section
  6. 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.

  7. 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
 Duo Push in Universal Prompt  Duo Push in Traditional Prompt

The Duo Google Chrome Enterprise application supports the Universal Prompt by default, so there's no additional action required on your part to start using the newest authentication experience.

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. Universal Prompt is already activated for new Google Chrome Enterprise applications at creation.

The "Universal Prompt" area of the application details page shows that this application's status is "Activation complete", 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" both here and on the Universal Prompt Update Progress report.

Universal Prompt Info - Universal Prompt Activation Complete

For the time being, you may change this setting to Show traditional prompt to use the legacy experience. Keep in mind that support for the traditional Duo prompt ended for the majority of applications in March 2024. This option will be removed in the future.

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

To log on to Google Chrome Enterprise SSO, do the following:

  1. Navigate to the Google Chrome Enterprise enrollment URL that you noted earlier. You will be automatically redirected to Duo Single Sign-On to begin authentication.

    Example: https://chromeenterprise.google/profile-enrollment/register?configuration=ABC123efg456HIJ789

  3. Click Continue to set up your Google Chrome profile. The You're all set! pop-up window opens.

  4. Click Continue.

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.

Duo Single Sign-On Login

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

Duo Single Sign-On Password

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 Google Chrome Enterprise to complete the login process.

Duo Universal Prompt

* Universal Prompt experience shown.

Google Chrome Enterprise 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 Google Chrome Enterprise 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.

Grant Access to Users

If you did not already grant user access to the Duo users you want to use this application be sure to do that before inviting or requiring them to log in with Duo.

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.

Automated Provisioning

When you configure creation and management of users and groups from Duo using SCIM 2.0 provisioning for , you have effectively configured provisioning for this application. Therefore, this application does not have its own automated provisioning configuration.

Make the Chrome Enrollment URL Visible to Duo Users

You can make your organization's Chrome Enterprise enrollment URL easier for your Duo users to find by following these suggestions:

  • Customize your help desk message with the enrollment URL.

    Edit the help desk message configuration in your Duo settings to add your organization's Chrome Enterprise enrollment URL in the "Links" section. When your users click the "Need help?" link in the MFA or passwordless Duo Universal Prompt they'll see the Chrome enrollment URL as a clickable link.

    Note that the help desk message applies to all applications; you can't choose which of your Duo applications show the Chrome enrollment link in the help message if you add it. Also, custom help desk messages aren't shown during Duo SSO username and password entry.

  • Bookmark the enrollment URL in Duo Central.

    Duo Central lets you bookmark external applications for quick access by users. Add a bookmark tile for your Chrome Enterprise enrollment URL.
