Firebox Access Portal Integration with Duo and AuthPoint

This document describes how to set up multi-factor authentication (MFA) for your Firebox Access Portal with Duo and AuthPoint.

Duo Single Sign-On is a cloud-hosted single sign-on solution. In this integration, Duo integrates with AuthPoint as an identity provider (IdP) and your Firebox Access Portal as the service provider (SP). AuthPoint provides the primary authentication and Duo SSO completes the secondary authentication.

Duo Single Sign-On does not officially support single logout (SLO).

17. From the Get Value From drop-down list, select User Groups.
18. To save the attribute, click Save.
19. To save the resource, click Save.

Add a Group in AuthPoint

You must have at least one user group in AuthPoint. If you already have a group, you do not have to add another group.

To add a WatchGuard Cloud-hosted group to the WatchGuard Cloud Directory:

1. Go to Configure > Directories and Domain Services.
2. Click the WatchGuard Cloud Directory domain name. If you have not yet added the WatchGuard Cloud Directory, click Add Authentication Domain and select the WatchGuard Cloud Directory.
   The New Group page appears.

3. In the Groups tab, click Add Group.
4. In the Group Name text box, type a descriptive name for the group.
5. (Optional) In the Description text box, type a description of the group.

6. Click Save.
   Your group is added to the WatchGuard Cloud Directory and to AuthPoint.

Add an Authentication Policy to AuthPoint

Authentication policies specify which resources users can authenticate to.

You must have at least one authentication policy in AuthPoint that includes the WatchGuard resource. If you already have authentication policies, you do not have to create a new authentication policy. You can add this resource to your existing authentication policies.

Users that do not have an authentication policy for a specific resource cannot authenticate to log in to that resource.

To configure an authentication policy:

1. From the navigation menu, select Authentication Policies.
2. Click Add Policy.
   The Add Policy page opens.



3. In the Name text box, type a name for this policy.
4. From the Select the Authentication Options drop-down list, select Authentication Options.
5. Select the Password check box.
6. For Groups, select which groups this policy applies to. You can select more than one group. To configure this policy to apply to all groups, select All Groups.
7. For Resources, select the resource that you created in the Add a SAML Resource in AuthPoint section. If you want this policy to apply to additional resources, select each resource this policy applies to. To configure this policy to apply to all resources, select All Resources.
8. (Optional) If you have configured policy objects such as Network Location, select which policy objects apply to this policy. When you add a policy object to a policy, the policy only applies to user authentications that match the conditions of the policy objects. For example, if you add a Network Location to a policy, the policy only applies to user authentications that come from that Network Location. Users who only have a policy that includes a Network Location do not get access to the resource when they authenticate outside of that Network Location (because they do not have a policy that applies, not because authentication is denied).

8. Click Save.
   Your policy is created and added to the end of the policy list.

When you create a new policy, we recommend that you review the order of your policies. AuthPoint always adds new policies to the end of the policy list.

Add Users to AuthPoint

Before you assign users to a group, you must add the users to AuthPoint. There are two ways to add AuthPoint user accounts:

• Sync users from an external user database
• Add WatchGuard Cloud-hosted AuthPoint users

Each user must be a member of a group. You must add at least one group before you can add users to AuthPoint.

Test the Integration

To test your Firebox Access Portal authentication integration with AuthPoint and Duo, you can authenticate with three methods: push, passkey, or phone call. In this example, we use the push authentication method. For more information about Duo Two-Factor Authentication, go to Two-Factor Authentication Guidelines in the Duo documentation.

If you do not create a user in Duo, a user is automatically created in Duo when you log in to Access Portal with SSO.

To test multi-factor authentication for your Access Portal with Duo and AuthPoint:

1. In a web browser, go to the Access Portal URL: https://<Host Name of Firebox SAML Authentication Server>.
   The login page opens with a button for the SAML authentication server you configured.



2. To log in, click the button for the SAML authentication server you created. In this example, we select Duo-SAML.
3. Type your email address or AuthPoint user name, then click Next.
4. In the Password text box, type your password.
5. Click Finish.
   Duo SSO prompts you to complete two-factor authentication.



6. Approve the push notification on your Duo Mobile app.
7. Tap Yes, This is My Device.
   You are logged in to the Access Portal.
