Please contact [Technical Support](https://go.servicetitan.com/#/ask) for details. ## Things to know - Setting up your account with the Lennox integration involves authenticating users through SingleSign-On (SSO). - When setting up your account for Lennox integration, the email and password are tied to an individual user, not the company. If Lennox removes the account of the main user who set up the integration, the integration will be disconnected, and you’ll need to reconnect it. > [!NOTE] > **Note**: We recommend setting up the integration with the business owner’s account credentials to avoid such scenarios. - If your integration disconnects, go to **Settings** ![A simple icon representing a settings gear.](https://cdn.document360.io/961862ab-d0f2-4d91-bb62-a62ee8184eff/Images/Documentation/icon-gnav-settings-inactive.png?sv=2026-02-06&spr=https&st=2026-10-31T01%3A47%3A03Z&se=2026-10-31T02%3A47%3A03Z&sr=c&sp=r&sig=DfWqOIv0yHNkXweCcdP6zYcRPDfrZWpOJpP%2FNWHPqFI%3D) **> Integrations > Vendor Integrations > Full Procurement** to reconnect.
