Duo Single Sign-On for 15Five

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 and zero-trust policies.

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 15Five 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 15Five.

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 15Five. Duo checks the user, device, and network against an application's policy before allowing access to the application.

Configure Single Sign-On

Before configuring 15Five with Duo SSO using Security Assertion Markup Language (SAML) 2.0 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 15Five application in Duo.

Create the 15Five Application in Duo

1. Log in to the Duo Admin Panel and navigate to Applications → Application Catalog.

2. Locate the entry for 15Five with the "SSO" label in the catalog. Click the + Add button to start configuring 15Five. See Protecting Applications for more information about protecting applications with Duo and additional application options. You'll need the information on the 15Five page under Metadata later.

3. No active Duo 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.

   This setting only applies to users who exist in Duo with "Active" status. This does not affect application access for existing users with "Bypass" status, existing users for whom the effective Authentication Policy for the application specifies "Bypass 2FA" or "Skip MFA", or users who do not exist in Duo when the effective New User Policy for the application allows access to users unknown to Duo without MFA.

4. 15Five uses the Mail attribute, First name attribute, and Last name attribute when authenticating. We've mapped these attributes to external authentication source attributes as follows:

   Default Attribute	Active Directory	SAML IdP
   <Email Address>	mail	Email
   <First Name>	givenName	FirstName
   <Last Name>	sn	LastName

   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.

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. 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

The Duo 15Five 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 15Five 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.

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.

Enable 15Five for SSO

1. Log into your 15Five account as an administrator.

2. In the top-right corner of the page, click the gear icon and then click Company settings. The "Settings: Company" page opens.

3. Click the SSO tab.

4. Enter your desired subdomain into the Subdomain field. Make note of your subdomain. You will need it later.

5. Click Save. You will be automatically redirected to your 15Five login page.

7. Make sure the SSO tab is selected.

8. Under "Single Sign-On", click Metadata & Contact.

9. Enter your email address into the Contact Email field.

10. Make sure the Automatically update metadata checkbox is not selected.

11. Return to the Duo Admin Panel. Under "Downloads", click Copy XML and paste the XML metadata text into the 15Five XML metadata field.

12. In 15Five, click Save.

13. To force users to log in with SSO, click the Allow Password Sign In checkbox to uncheck it.

14. Click the Name ID Contents drop-down menu and select Email.

15. Scroll down to "User Attributes". Type the following into their respective fields:

    • Type email into the Email attribute name field.

    • Type firstname into the First name attribute name field.

    • Type lastname into the Last name attribute name field.

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

17. Return to the Duo Admin Panel. Under "Service Provider", type https://yoursubdomain.15five.com/saml2/metadata/ using the subdomain you noted earlier and then click Populate.

    

18. In the Duo Admin Panel, scroll down to the bottom of the page and click Save.

Using SSO

You can log on to 15Five by navigating to your 15Five SSO page e.g., https://yoursubdomain.15five/com. Click Sign in using Single Sign-on 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

The SAML login experience depends on your Duo SSO routing rules configuration.

With another SAML identity provider as the only enabled Duo SSO authentication source and the default routing rule in place, Duo SSO immediately redirects the login attempt to that SAML IdP for primary authentication. Users do not see the Duo SSO primary login screen.

If you have multiple enabled SAML authentication sources or custom routing rules in place, then users enter their primary username (email address) on the Duo SSO login page and then will be redirected to the correct external SAML identity provider.

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 15Five to complete the login process.

* Universal Prompt experience shown.

You can also log into 15Five using Duo Central, our cloud-hosted portal which allows users to access all of their applications in one spot. Link to 15Five 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 IdP-initiated authentication to 15Five.

Congratulations! Your 15Five 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 15Five and your other Duo Single Sign-On SAML applications, be sure to apply a shared "Remembered Devices" policy to your SAML applications.

Automated Provisioning

You may be able to create, manage, and delete users and groups in this application automatically from Duo using SCIM 2.0 provisioning. See Automated Provisioning to learn how.
