# Set up a Cisco Duo connector

> C1 provides identity governance for Duo. Integrate your Duo instance with C1 to run user access reviews (UARs) and enable just-in-time access requests.

## Availability

This connector uses the Duo Admin API, which is available to users on the Duo Premier, Advantage, and Essentials plans.

## Capabilities

| Resource | Sync                                                          | Provision                                                     |

## Gather Duo credentials

Configuring the connector requires you to pass in credentials generated in Duo. Gather these credentials before you move on.

<Warning>
  A user with the **Owner** role in Duo must perform this task.
</Warning>

<Steps>
  <Step>
    Log into the Duo Admin Panel and navigate to **Applications**.
  </Step>

  <Step>
    Click **Protect an Application** and locate the entry for **Admin API** in the applications list.
  </Step>

  <Step>
    Click **Protect**.
  </Step>

  <Step>
    In the **Permissions** section, grant the following permissions based on your use case:

    **Required for sync (read-only):**

    * Grant administrators — Read
    * Grant read information
    * Grant settings
    * Grant resource — Read

    **Also required for provisioning (group membership):**

    * Grant resource — Write
  </Step>

  <Step>
    Click **Save changes**. Scroll to the **Details** section, where the integration key, secret key, and API hostname are shown, and carefully copy and save these credentials.
  </Step>
</Steps>

**Done.** Next, move on to the connector configuration instructions.

## Configure the Duo connector

<Warning>
  To complete this task, you'll need:

  * The **Connector Administrator** or **Super Administrator** role in C1
  * Access to the set of Duo credentials generated by following the instructions above
</Warning>

<Tabs>
  <Tab title="Cloud-hosted">
    **Follow these instructions to use a built-in, no-code connector hosted by C1.**

    <Steps>
      <Step>
        In C1, navigate to **Integrations** > **Connectors** and click **Add connector**.
      </Step>

      <Step>
        Search for **Duo** and click **Add**.
      </Step>

      <Step>
        Choose how to set up the new Duo connector:

        * Add the connector to a currently unmanaged app (select from the list of apps that were discovered in your identity, SSO, or federation provider that aren't yet managed with C1)
        * Add the connector to a managed app (select from the list of existing managed apps)
        * Create a new managed app
      </Step>

      <Step>
        Set the owner for this connector. You can manage the connector yourself, or choose someone else from the list of C1 users. Setting multiple owners is allowed.

        If you choose someone else, C1 will notify the new connector owner by email that their help is needed to complete the setup process.
      </Step>

      <Step>
        Click **Next**.
      </Step>

      <Step>
        Find the **Settings** area of the page and click **Edit**.
      </Step>

      <Step>
        Enter the credentials into the **Integration key**, **Secret key**, and **API hostname** fields.
      </Step>

      <Step>
        Click **Save**.
      </Step>

      <Step>
        The connector's label changes to **Syncing**, followed by **Connected**. You can view the logs to ensure that information is syncing.
      </Step>
    </Steps>

    **Done.** Your Duo connector is now pulling access data into C1.
  </Tab>

  <Tab title="Self-hosted">
    **Follow these instructions to use the Duo connector, hosted and run in your own environment.**

    When running in service mode on Kubernetes, a self-hosted connector maintains an ongoing connection with C1, automatically syncing and uploading data at regular intervals. This data is immediately available in the C1 UI for access reviews and access requests.

    ### Step 1: Set up a new Duo connector

    <Steps>
      <Step>
        In C1, navigate to **Integrations** > **Connectors** > **Add connector**.
      </Step>

      <Step>
        Search for **Baton** and click **Add**.
      </Step>

      <Step>
        Choose how to set up the new Duo connector:

        * Add the connector to a currently unmanaged app (select from the list of apps that were discovered in your identity, SSO, or federation provider that aren't yet managed with C1)
        * Add the connector to a managed app (select from the list of existing managed apps)
        * Create a new managed app
      </Step>

      <Step>
        Set the owner for this connector. You can manage the connector yourself, or choose someone else from the list of C1 users. Setting multiple owners is allowed.

        If you choose someone else, C1 will notify the new connector owner by email that their help is needed to complete the setup process.
      </Step>

      <Step>
        Click **Next**.
      </Step>

      <Step>
        In the **Settings** area of the page, click **Edit**.
      </Step>

      <Step>
        Click **Rotate** to generate a new Client ID and Secret.

        Carefully copy and save these credentials. We'll use them in Step 2.
      </Step>
    </Steps>

    ### Step 2: Create Kubernetes configuration files

    Create two Kubernetes manifest files for your Duo connector deployment:

    #### Secrets configuration

    ```yaml expandable theme={"theme":{"light":"css-variables","dark":"css-variables"}}
    # baton-duo-secrets.yaml
    apiVersion: v1
    kind: Secret
    metadata:
      name: baton-duo-secrets
    type: Opaque
    stringData:
      # C1 credentials
      BATON_CLIENT_ID: <C1 client ID>
      BATON_CLIENT_SECRET: <C1 client secret>
      
      # Duo credentials
      BATON_API_HOSTNAME: <Duo API hostname>
      BATON_INTEGRATION_KEY: <Duo integration key>
      BATON_SECRET_KEY: <Duo secret key>

      # Optional: include if you want C1 to provision access using this connector
      BATON_PROVISIONING: true
    ```

    See the connector's README or run `--help` to see all available configuration flags and environment variables.

    #### Deployment configuration

    ```yaml expandable theme={"theme":{"light":"css-variables","dark":"css-variables"}}
    # baton-duo.yaml
    apiVersion: apps/v1
    kind: Deployment
    metadata:
      name: baton-duo
      labels:
        app: baton-duo
    spec:
      selector:
        matchLabels:
          app: baton-duo
      template:
        metadata:
          labels:
            app: baton-duo
            baton: true
            baton-app: duo
        spec:
          containers:
          - name: baton-duo
            image: ghcr.io/conductorone/baton-duo:latest
            imagePullPolicy: IfNotPresent
            env:
            - name: BATON_HOST_ID
              value: baton-duo
            envFrom:
            - secretRef:
                name: baton-duo-secrets
    ```

    ### Step 3: Deploy the connector

    <Steps>
      <Step>
        Create a namespace in which to run C1 connectors (if desired), then apply the secret config and deployment config files.
      </Step>

      <Step>
        Check that the connector data uploaded correctly. In C1, click **Apps**. On the **Managed apps** tab, locate and click the name of the application you added the Duo connector to. Duo data should be found on the **Entitlements** and **Accounts** tabs.
      </Step>
    </Steps>

    **Done.** Your Duo connector is now pulling access data into C1.
