Based on our system's design, double onboarding with the same organization (i.e., having two separate registrations ) is not possible in the sense that resources allocated to a specific organizationidentifier (TPP-ID) in QWAC certificate cannot be shared across different TPP IDs. Each TPP registration is uniquely tied to an organization identifier, and resources are allocated accordingly.
Our system allows the use of multiple certificates , each associated with a unique organization identifier. However, please note that resources created under one certificate (for example, a consent created with a specific certificate) can only be accessed using that same certificate. Resources are not transferable or shareable across different certificates.
If you require access to resources created under different certificates, separate requests must be made through the corresponding organization identifiers linked to those specific certificates. It is not possible to access resources between both of your certificates through it belongs to same organisation and our system identifies as different entity as far organization identifier changes.
There is one edge case here, we can have two certificates per organization identifier during that particular certificate renewal process. While one certificate is about to expire and other one is already renewed then both certificates can be used together without any issues and no trouble in accessing the resources as long as organization identifier is same in both certificates.
