The criteria for Access to Accounts
In Europe, the regulator has stepped in and defined in PSD2 a strict set of rules with which each bank must comply:

Fully Integrated, Standardized and Scalable – Omikron’s Approach
In order to ensure rapid market maturity and implement new standards quickly, Omikron’s design is closely aligned with the specification standards of the Berlin Group. Using the REST-API provided, ISO 20022-formats and JSON-formats are exchanged and processed using the existing internal workflow. For authorization, users can work with the existing familiar signature method.
The XS2A Connector module consists of two components:

The Authentication Server
The Authentication Server handles the authentication in the third-party scenario. Each Third Party Provider owns a qualified certificate as defined in the PSD2 requirements. The Omikron Authentication Server is responsible for the identification of third parties based on the established Public-Key-Infrastructure with qualified certificates. These certificates will be issued to registered third parties by approved certificate authorities. The Omikron Authentication Server verifies the validity of the certificates.
