Permissions can be delegated to enable access to resources associated with one or more different accounts, which might be associated with one or more different entities. Accordingly, approaches for delegating security rights and privileges for services and resources in an electronic and/or multi-tenant environment are provided. In particular, various embodiments provide approaches for dynamically determining and authorizing delegation of permissions to perform actions in, on, or against one or more secured accounts, where those accounts may be associated with a number of different entities and/or resource providers.
