US Patent 11930016 Authentication framework for resource access across organizations

A client application is specified by a target tenant and represented in an OAuth provider, along with a corresponding secret. A source tenant consents to permissions to be executed by the client application on a resource of the source tenant. A target service uses the secret to obtain an access token from an authorization server coupled to the source tenant and uses the access token to obtain access, specified by the permissions, to the resource served by a source service acting on behalf of the source tenant.
