 | **Domain** | Enter the domain name for your Azure directory (such as `fishtownanalytics.com`). Only use the primary domain; this won't block access for other domains. |

Users will be able to log into dbt Cloud by navigating to `https://YOUR_ACCESS_URL/enterprise-login/LOGIN-SLUG`, replacing `YOUR_ACCESS_URL` with the [appropriate Access URL](/docs/cloud/manage-access/sso-overview#auth0-multi-tenant-uris) for your region and plan. Login slugs must be unique across all dbt Cloud accounts, so pick a slug that uniquely identifies your company. |
