+## Integrate with SharePoint and OneDrive
+
+You can [enable integration with SharePoint and OneDrive](/sharepoint/sharepoint-azureb2b-integration) to share files, folders, list items, document libraries, and sites with people outside your organization, while using Azure B2B for authentication and management. The users you share resources with are typically added to your directory as guests, and permissions and groups work the same for these guests as they do for internal users. When enabling integration with SharePoint and OneDrive, you'll also enable the [email one-time passcode](one-time-passcode.md) feature in Azure AD B2B to serve as a fallback authentication method.
