# Configuring a SAML 2.0 External Identity Provider

> Set up AD FS or Azure Active Directory (Azure AD) as a SAML 2.0 External Identity Provider for your ABBYY Vantage tenant.

Set up AD FS or Azure AD as a SAML 2.0 External Identity Provider for your Vantage tenant. Each guide below walks through the provider-side configuration; once that's complete, [connect the provider to your Vantage tenant](/vantage/documentation/tenant-admin/tenant-management/configuring-tenant).

<Note>
  This setup requires the **Tenant Administrator** role.
