This document describes how to set up multi-factor authentication (MFA) for your Google G Suite with AuthPoint, and configure SAML authentication with AuthPoint as an identity provider.
Google G Suite must already be configured and deployed before you set up MFA with AuthPoint. Google G Suite can be configured to support MFA in several modes. For this integration, we set up SAML with AuthPoint.
Google G Suite Authentication Data Flow with AuthPoint
AuthPoint communicates with various cloud-based services and service providers with the SAML protocol. This diagram shows the data flow of an MFA transaction for Google G Suite.
Before You Begin
Before you begin these procedures, make sure that:
- End-users can log in to the Google G Suite
- A token is assigned to a user in AuthPoint
- You have an AuthPoint identity provider (IdP) certificateAn AuthPoint IdP certificate is required for SAML authentication. (see Certificate Management)
Configure Google G Suite
To start, you must download the metadata file from the Resources page in the AuthPoint management UI. Once you have the metadata file, you can configure Google G Suite.
- Log in to WatchGuard Cloud.
- From the navigation menu, select Configure > AuthPoint. If you have a Service Provider account, you must first pivot to your Subscriber view.
- Select Resources.
- Click Certificate.
- Next to AuthPoint certificate you will associate with your resource, click and select Download Metadata and Download Certificate.
We recommend that you choose the certificate with the latest expiration date.
The AuthPoint metadata provides your resource, in this case Google, with information necessary to identify AuthPoint as a trusted identity provider.
- Log in to the Admin Console of your account as an administrator.
- Click Security.
- On the Security page, select Set up single sign-on (SSO).
- On the SSO Settings page, select Setup SSO with third party identity provider.
- Click Upload and browse to select the AuthPoint certificate file you downloaded.
- Fill out the Sign-in page URL and Sign-out page URL text boxes with the values from the AuthPoint metadata file you downloaded.
- Click Save.
Before AuthPoint can receive Google G Suite authentication requests from Google G Suite, you must specify the Google G Suite client in AuthPoint. You must also assign the Google G Suite to the user group that will authenticate through Google G Suite.
Add a SAML Resource in AuthPoint
From the AuthPoint management UI:
- From the navigation menu, select Resources.
- From the Choose a Resource Type drop-down list, select SAML. Click Add Resource.
- In the Service Provider Entity ID text box, type google.com/a/<your domain>.
- In the Assertion Consumer Service text box, type https://www.google.com/a/<your domain>/acs.
- Click Save.
Add an Access Policy to AuthPoint
You must have at least one user group in AuthPoint for authentication with Google G Suite, and you must assign an access policy for the Google G Suite resource to that group. If you already have a group, you do not have to add another group.
In the AuthPoint management UI:
- From the navigation menu, select Groups.
- To add a new group, click Add Group. If you already have a group that you want to use, select the group to edit it.
- In the Name text box, type a descriptive name for the group.
- (Optional) In the Description text box, type a description of the group.
- In the Access Policy section, click Add Policy.
- In the Add Policy dialog box, from the Resource drop-down list, select the resource you want to add an access policy for.
- (Optional) To require that users type their password before they authenticate for this resource, select the Require Password Authentication slider.
- Select the authentication options that users in this group can choose from when they authenticate.
For SAML resources, if you select more than one authentication option, users must choose one of the available options when they authenticate. For example, if you select OTP and Push, users can choose to type their OTP or approve a push to authenticate. You cannot require that they do both.
- Click Add.
- (Optional) Add one or more safe locations to your group. For more information about safe locations and detailed instructions to add them, see About Safe Locations.
- Click Save.
Before you assign users to a group, you must add them to AuthPoint. You can manually add user accounts or import user accounts from your LDAP database. For more information on how to add user accounts, see Add User Accounts.
Test the Integration
To test the integration of AuthPoint and Google G Suite, you can authenticate with a mobile token on your mobile device. You can choose any method (one-time password, QR code, or push).
In this example, we show the push authentication method (users receive a push notification in the mobile app that they must approve to authenticate).
In a web browser, go to the Google G Suite URL.
SSO is for web based applications of Google. If you go to the admin console with a super admin account, you will bypass SSO.
- Type your email address or AuthPoint user name. Click Next.
- If required, in the Password text box, type your password.
- For the authentication method, select Push.
- Click Send.
- Approve the authentication request that is sent to your mobile device.
You are logged in to Google G Suite.
