What is a certificate? How is it related to an AOR?
A certificate is digitally signed information that allows the Grants.gov system to identify your system and securely exchange information with it. Just as GUI users provide a user ID and password to identify themselves, S2S clients use a certificate (rather than storing user ID’s and passwords in code). The primary difference between the two methods is that certificates identify your system but may or may not identify the individual user, i.e. an Authorized Organization Representative (AOR). Your system is responsible for ensuring that only AORs can submit applications. Associating your certificate with an AOR is part of the registration process for S2S users.
