Embodiments relate to systems, devices, and computer-implemented methods for providing secure access to a shared registration system of a domain name registry by generating authorization information associated with a domain name, storing the authorization information in an archive, receiving, from a non-registrar service provider, a request for access to functionality of a shared registration system of the domain name registry, where the request is associated with the domain name and includes authorization information, determining whether the received authorization information is valid using the archived authorization information, and allowing the non-registrar service provider access to the functionality of the SRS based on a determination that the second authorization information is valid.
