You can preauthenticate an application using the Code Grant Flow from OAuth2 when running a product such as Invantive Data Replicator or Invantive Data Hub on hardware under control of your company. "Preauthentication" creates application settings (including a refresh token) which enable access to Exact Online using an application without further security credentials exchange. The process can be executed before the actual use of the application. Invantive Preauthentication has no resemblance with Kerberos Preauthentication.
SECURITY WARNING! A two-step authentication to achieve strong authentication is only applied during preauthentication. Apply additional measures such as IP-based access control or hardware-bound encryption of the token when you require continuous strong authentication after preauthentication. This limitation holds for ALL apps based on Exact Online. Please consult your security officer when in doubt.
Please enter the application information you have received from the Invantive consultant, your Invantive dealer or directly from the Exact App Center application registration. For questions, please read up on OAuth security concerns and when necessary contact Invantive Support.
