Duo Single Sign-On for Cisco Webex (with Control Hub)

Last Updated: July 28th, 2020

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

Webex Meetings and Webex Teams desktop clients do not currently support Trusted Endpoints.

If your administrator login URL is continue below. If not, please see our generic service provider application.


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

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 Webex 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 Webex.

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

Configure Single Sign-On

Before configuring Webex you'll first need to configure Duo Single Sign-On with a working an authentication source.

Locate your Cisco Webex Organization ID

  1. Log into Control Hub as an administrative user.

  2. Click on the name of your company in the lower left-hand side navigation bar.

  3. On the “My Company” page locate the Organization ID. Make note of it as you will need it later.

Create the Webex 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 Cisco Webex (with Control Hub) 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 Cisco Webex (with Control Hub). See Protecting Applications for more information about protecting applications in Duo and additional application options. You'll need the information on the Cisco Webex (with Control Hub) page under Metadata later.

  3. Enter the organization ID you made note of earlier into Organization ID.

  4. Webex uses the Mail attribute when authenticating. We've mapped the <Email Address> bridge attribute to Duo Single Sign-On supported authentication source attributes as follows:

    Bridge Attribute Active Directory SAML IdP
    <Email Address> mail Email

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

  5. 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.

  6. Scroll to the bottom of the page and click the Save button.

Configure Webex SSO in Control Hub

  1. Return to Control Hub as an administrative user.

  2. Click on Settings in the left-hand navigation bar.

  3. Next to “Authentication” click Modify. A pop-up will appear with new options.

  4. On the “Single Sign-On” page select Integrate a 3rd-party identity provider. (Advanced) and click Next.

  5. On the “Export Directory Metadata” page click Next.

  6. On “Import IdP Metadata” under “Signing of Metadata” select Allow self-signed certificate in Metadata.

  7. Click Download XML next to the "IdP Metadata file" button on the Webex application's page in the Duo Admin Panel under Downloads to download the Duo Single Sign-On XML file. On the Webex administrative page upload the XML metadata file you downloaded. Click Next.

  8. On the “Test SSO Setup” page click Test SSO Connection. A new page will open and you’ll be redirected to login with the Duo Single Sign-On by completing primary authentication and Duo second-factor. Upon successful login you’ll be taken to a page that says “Single Sign-on succeeded.” Close this window and return to the Control Hub page.

  9. As long as the authentication was successful select The test was successful. Enable Single Sign On. and click Next. If it was not successful, double-check instructions and settings. Do not continue until you get a successful test authentication.

  10. Once the settings successfully save you’ll be returned to the “Settings” page and SSO will be enabled for Webex.

Verify SSO

You can log on by navigating to Webex Login. Type your e-mail address the text field and click Next. You'll be redirected 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 Webex site after authenticating.

Duo Single Sign-On Login and Authentication Prompt

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

Users can also log in using their desktop and mobile app clients for Webex Meetings and Webex Teams.

Enable Remembered Devices

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

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 Webex. Learn more about configuring Webex SSO with AD FS at the Webex Help site.

After you have successfully configured and tested AD FS SSO login to Webex 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 Webex.

Other Identity Partners

Using a third-party SSO provider for cloud application access? Duo partners with leading cloud SSO providers like Okta and OneLogin to secure access with our strong and flexible authentication platform.

You can also use Duo two-factor authentication with CAS and Shibboleth on-premises IdPs.
