[role="_abstract"] When integrating with a third party like a customer or business partner, you might want to manage their identities separately from others and build a unified and secure experience throughout your business ecosystem when they interact with a realm. In a realm, an *organization* represents these third parties so that a realm or an organization administrator can manage the entire lifecycle of its members and how they authenticate and authorize to a realm, on a per-organization basis. The organization is the entry point to start using the IAM capabilities of {project_name} to also address Business-to-Business (B2B) use cases. It enables multi-tenancy within a realm so that users can have access to protected resources from a realm but with a more restricted and controlled context, that context being the organization to which they belong. {project_name} Organizations is a feature that enables support for organizations in {project_name}. For now, it provides some of the core capabilities needed to manage organizations such as: * Manage members * Onboard organization members using invitation links * Onboard organization members by federating their identities through identity brokering * Identity-first login and organization-specific steps when authenticating in the scope of an organization * Propagate organization-specific claims to applications through tokens for authorization purposes
