 # Create dynamic groups in Azure Active Directory B2B collaboration
 
 ## What are dynamic groups?
-Dynamic configuration of security group membership for Azure Active Directory (Azure AD) is available in [the Azure portal](https://portal.azure.com). Administrators can set rules to populate groups that are created in Azure AD based on user attributes (such as [userType](user-properties.md), department, or country/region). Members can be automatically added to or removed from a security group based on their attributes. These groups can provide access to applications or cloud resources (SharePoint sites, documents) and to assign licenses to members. Read more about dynamic groups in [Dedicated groups in Azure Active Directory](../fundamentals/active-directory-groups-create-azure-portal.md).
