# Run and Manage Identification

**Requirement**: Immuta permission `GOVERNANCE` or domain-specific `Manage Identifiers`

Identification can be configured to run automatically or manually on a domain-by-domain basis. If you want to re-run identification when a data source or new identifiers have been added to a domain, you can [manually run it for the domain using the API](https://documentation.immuta.com/saas/developer-guides/api-intro/immuta-v1-api/configure-your-instance-of-immuta/manage-identifiers-in-domains#post-sdd-identification) or from the UI.

## Configure a domain's autoscanning setting <a href="#configure-a-domains-autoscanning-setting" id="configure-a-domains-autoscanning-setting"></a>

1. Click <i class="fa-globe">:globe:</i> **Domains** in the navigation menu and select your domain.
2. Click the **Settings** tab.
3. Select the autoscanning on the toggle:
   * **On**: Identification will automatically run when new data sources are added to the domain or when object sync detects new columns on data sources already in the domain.
   * **Off**: Identification will only run when manually started by a user.

## Run identification in a domain <a href="#run-identification-in-a-domain" id="run-identification-in-a-domain"></a>

## Run identification on a data source <a href="#run-identification-on-a-data-source" id="run-identification-on-a-data-source"></a>

1. Navigate to the data source overview page.
2. Click the health status.

{% hint style="info" %}
**Verify tags**

When using identification, manually adding tags to columns in the data source will be unnecessary in most cases. The data owner will just need to verify that the applied tags are correct.
{% endhint %}

### Disable tags from the data source columns <a href="#disable-tags-from-the-data-dictionary" id="disable-tags-from-the-data-dictionary"></a>

If a governor, data owner, or data source expert disables a tag from the data source column applied by identification, the column will not be re-tagged next time identification runs. When a tag is disabled, it will not completely disappear, and it can be manually enabled through the tag side sheet.

To disable a tag,

1. Navigate to a data source and click the **Columns** tab.
2. Scroll to the **column** you want to remove the tag from and click the tag you want to remove.
3. Click **Disable** in the side sheet and then click **Confirm**.
