Duo Single Sign-On for Workday

Last Updated: May 26th, 2020

Add two-factor authentication and flexible security policies to Workday SSO logins with Duo Single-Sign On, our cloud-hosted SAML 2.0 identity provider, complete with inline self-service enrollment and Duo Prompt.

To apply Duo MFA policies to non-SSO Workday logins via authentication policy rules, refer to the Workday instructions.

Overview

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 Workday 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 Workday.

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

Configure Single Sign-On

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

Create the Workday 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 Workday 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 Workday. See Protecting Applications for more information about protecting applications in Duo and additional application options. You'll need the information on the Workday page under Metadata later.

  3. Enter your Workday Tenant URL used when logging into your company's Workday Tenant as the Workday Tenant URL. For example, if your Workday Tenant URL is https://myworkday.com/abc then enter myworkday.com/abc.

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

    Bridge Attribute Active Directory SAML IdP
    <Username> sAMAccountName Username

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

    Configure Workday Redirect URLs

Using SSO

You can log on to Workday Tenant by navigating to your Workday Tenant URL e.g. https://myworkday.com/abc. This redirects 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 Workday site after authenticating.

Duo Single Sign-On Login and Authentication Prompt

If using the Workday mobile app, you will be automatically redirected to authenticate to Duo Single Sign-On.

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

Enable Remembered Devices

To minimize additional Duo two-factor prompts when switching between Workday 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 Workday. Learn more about configuring Workday SSO with AD FS at the Workday Community site.

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

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.
