+title: "Google SAML"
+description: "Configure Google SAML for Infisical SSO"
+---
+
+<Info>
+    Google SAML SSO feature is a paid feature.
+   
+    If you're using Infisical Cloud, then it is available under the **Pro Tier**. If you're self-hosting Infisical,
+    then you should contact [email protected] to purchase an enterprise license to use it.
+</Info>
+
+<Steps>
+   <Step title="Prepare the SAML SSO configuration in Infisical">
+        In Infisical, head to your Organization Settings > Authentication > SAML SSO Configuration and select **Set up SAML SSO**.
+
+        Next, note the **ACS URL** and **SP Entity ID** to use when configuring the Google SAML application.
+      
+        ![Google SAML initial configuration](../../../images/sso/google-saml/init-config.png)
+   </Step>
+   <Step title="Create a SAML application in Google">
+        2.1. In your [Google Admin console](https://support.google.com/a/answer/182076), head to Menu > Apps > Web and mobile apps and
+        create a **custom SAML app**.
+        
+        ![Google SAML app creation](../../../images/sso/google-saml/create-custom-saml-app.png)
+        
+        2.2. In the **App details** tab, give the application a unique name like Infisical.
+        
+        ![Google SAML app naming](../../../images/sso/google-saml/name-custom-saml-app.png)
+        
+        2.3. In the **Google Identity Provider details** tab, copy the **SSO URL**, **Entity ID** and **Certificate**.
+        
+        ![Google SAML custom app details](../../../images/sso/google-saml/custom-saml-app-config.png)
+        
+        2.4. Back in Infisical, set **SSO URL**, **IdP Entity ID**, and **Certificate** to the corresponding items from step 2.3.
+        
+        ![Google SAML Infisical config](../../../images/sso/google-saml/infisical-config.png)
+        
+        2.5. Back in the Google Admin console, in the **Service provider details** tab, set the **ACS URL** and **Entity ID** to the corresponding items from step 1.
+
+        Also, check the **Signed response** checkbox.
+
+        ![Google SAML app config 2](../../../images/sso/google-saml/custom-saml-app-config-2.png)
+        
+        2.6. In the **Attribute mapping** tab, configure the following map:
+
+        - **First name** -> **firstName**
+        - **Last name** -> **lastName**
+        - **Primary email** -> **email**
+
+        ![Google SAML attribute mapping](../../../images/sso/google-saml/attribute-mapping.png)
+        
+        Click **Finish**.
+    </Step>
+    <Step title="Assign users in Google Workspace to the application">
+        Back in your [Google Admin console](https://support.google.com/a/answer/182076), head to Menu > Apps > Web and mobile apps > your SAML app
+        and press on **User access**.
+
+        ![Google SAML user access](../../../images/sso/google-saml/user-access.png)
+        
+        To assign everyone in your organization to the application, click **On for everyone** or **Off for everyone** and then click **Save**.
+        
+        You can also assign an organizational unit or set of users to an application; you can learn more about that [here](https://support.google.com/a/answer/6087519?hl=en#add_custom_saml&turn_on&verify_sso&&zippy=%2Cstep-add-the-custom-saml-app%2Cstep-turn-on-your-saml-app%2Cstep-verify-that-sso-is-working-with-your-custom-app).
+        
+        ![Google SAML user access assignment](../../../images/sso/google-saml/user-access-assign.png)
+    </Step>
+    <Step title="Enable SAML SSO in Infisical">
+        Enabling SAML SSO allows members in your organization to log into Infisical via Google Workspace.
+
+        ![Google SAML enable](../../../images/sso/google-saml/enable-saml.png)
+    </Step>
+    <Step title="Enforce SAML SSO in Infisical">
+        Enforcing SAML SSO ensures that members in your organization can only access Infisical
+        by logging into the organization via Google.
+
+        To enforce SAML SSO, you're required to test out the SAML connection by successfully authenticating at least one Google user with Infisical;
+        Once you've completed this requirement, you can toggle the **Enforce SAML SSO** button to enforce SAML SSO.
+        
+        <Warning>
+            We recommend ensuring that your account is provisioned the application in Google
+            prior to enforcing SAML SSO to prevent any unintended issues.
+        </Warning>
+    </Step>
+</Steps>
+
+<Note>
+   If you're configuring SAML SSO on a self-hosted instance of Infisical, make sure to
+   set the `AUTH_SECRET` and `SITE_URL` environment variable for it to work:
+   
+   - `AUTH_SECRET`: A secret key used for signing and verifying JWT. This can be a random 32-byte base64 string generated with `openssl rand -base64 32`.
+   - `SITE_URL`: The URL of your self-hosted instance of Infisical - should be an absolute URL including the protocol (e.g. https://app.infisical.com)
+</Note>
