This article contains Google Workspace-specific help for configuring Login with SSO via SAML 2.0. For help configuring Login with SSO for another IdP, refer to SAML 2.0 Configuration.

Configuration involves working simultaneously with the Bitwarden Business Portal and the Google Workspace Admin console. As you proceed, we recommend having both readily available and completing steps in the order they're documented.

Open the Business Portal

If you're coming straight from SAML 2.0 Configuration, you should already have an Organization ID created and the SSO Configuration screen open. If you don't, open your Business Portal and navigate to the SSO Configuration screen:

{% image sso/sso-saml1.png SAML 2.0 Configuration %}

You don't need to edit anything on this screen yet, but keep it open for easy reference.

Create a SAML app

In the Google Workspace Admin console, select Apps → SAML apps from the navigation:

{% image sso/cheatsheets/saml-google/g-addapp.png SAML Apps %}

Select Add App → Add custom SAML app:

{% image sso/cheatsheets/saml-google/g-addapp2.png Custom SAML App %}

App details

On the App details screen, give the application a unique Bitwarden-specific name and select the Continue button.

Google Identity Provider details

On the Google Identity Provider details screen, copy your SSO URL, Entity ID, and Certificate for use during a later step.

Select Continue when you're finished.

Service provider details

On the Service provider details screen, configure the following fields:

Field	Description
ACS URL	Set this field to the pre-generated Assertion Consumer Service (ACS) URL retrieved from the Bitwarden SSO configuration screen. For Cloud-hosted customers, this is always https://sso.bitwarden.com/saml2/your-org-id/Acs. For self-hosted instances, this is determined by your configured server URL, for example https://your.domain/sso/your-org-id/Acs.
Entity ID	Set this field to the pre-generated SP Entity ID retrieved from the Bitwarden SSO Configuration screen. For Cloud-hosted customers, this is always https://sso.bitwarden.com/saml2. For self-hosted instances, this is determined by your configured server URL, for example https://your.domain.com/sso/saml2.
Start URL	Optionally, set this field to the login URL from which users will access Bitwarden. For Cloud-hosted customers, this is always https://vault.bitwarden.com/#/sso. For self-hosted instances, this is determined by your configured server URL, for example https://your.domain.com/#/sso.
Signed response	Check this box if you want Workspace to sign SAML responses. If not checked, Workspace will sign only the SAML assertion.
Name ID format	Set this field to the SAML NameID format{:target="_blank"} for Workspace to use in SAML responses.
Name ID	Select the Workspace user attribute to populate NameID.

Select Continue when you're finished.

Attribute mapping

On the Attribute mapping screen, select the Add Mapping button and construct the following mapping:

Google Directory attributes	App attributes
Primary email	email

Select Finish.

Turn On the App

By default, Workspace SAML apps will be OFF for everyone. Open the User Access section for the SAML app and set to ON for everyone or for specific Groups, depending on your needs:

{% image sso/cheatsheets/saml-google/g-activate.png User Access %}

Save your changes.

Back to the Business Portal

At this point, you've configured everything you need within the context of the Google Workspace Admin console. Jump back over to the Bitwarden Business Portal to complete configuration.

The Business Portal separates configuration into two sections:

• SAML Service Provider Configuration will determine the format of SAML requests.
• SAML Identity Provider Configuration will determine the format to expect for SAML responses.

Service Provider Configuration

Configure the following fields according to the choices selected in the Workspace Admin console during setup:

Field	Description
Name ID Format	Set this field to the Name ID format selected in Workspace.
Outbound Signing Algorithm	The algorithm Bitwarden will use to sign SAML requests.
Signing Behavior	Whether/when SAML requests will be signed.
Minimum Incoming Signing Algorithm	By default, Google Workspace will sign with RSA SHA-256. Select sha-256 from the dropdown.
Want Assertions Signed	Whether Bitwarden expects SAML assertions to be signed. By default, Workspace SAML Apps will sign SAML assertions, so you may check this box.
Validate Certificates	Check this box when using trusted and valid certificates from your IdP through a trusted CA. Self-signed certificates may fail unless proper trust chains are configured with the Bitwarden Login with SSO docker image.

When you're done with the Service Provider Configuration section, Save your work.

Identity Provider Configuration

Identity Provider Configuration will often require you to refer back to the Workspace Admin console to retrieve application values:

Field	Description
Entity ID	Set this field to Workspace's Entity ID, retrieved from the Google Identity Provider details section or using the Download Metadata button.
Binding Type	Set to HTTP POST or Redirect.
Single Sign On Service URL	Set this field to Workspace's SSO URL, retrieved from the Google Identity Provider details section or using the Download Metadata button.
Single Log Out URL	Login with SSO currently does not support SLO. This option is planned for future development, however you may pre-configure it if you wish.
Artifact Resolution Service URL	For Workspace SAML app implementations, leave this field blank.
X509 Public Certificate	Paste the retrieved Certificate, removing -----BEGIN CERTIFICATE----- and -----END CERTIFICATE-----. Extra spaces, carriage returns, and other extraneous characters will cause certifiation validation to fail.
Outbound Signing Algorithm	By default, Google Workspace will sign with RSA SHA-256. Select sha-256 from the dropdown.
Allow Unsolicited Authentication Response	Login with SSO currently does not support unsolicited (IdP-initiated) SAML assertions. This option is planned for future development.
Disable Outbound Logout Requests	Login with SSO currently does not support SLO. This option is planned for future development.
Want Authentication Requests Signed	Whether Google Workspace expects SAML requests to be signed.

When you're done with the Identity Provider Configuration section, Save your work.

Test the Configuration

Once your configuration is complete, test it by navigating to https://vault.bitwarden.com{:target="_blank"} and selecting the Enterprise Single Sign-On button:

{% image sso/sso-button-lg.png Enterprise Single Sign-On button %}

Enter the configured Organization Identifier and select Log In. If your implementation is successfully configured, you'll be redirected to the Google Workspace login screen:

{% image sso/cheatsheets/saml-google/g-login.png Login %}

After you authenticate with your Workspace credentials, enter your Bitwarden Master Password to decrypt your Vault!
