The increase in the number of online services emphasizes the value of authentication and identity management that we, even without realizing, depend on. In EPOS this authentication and identity management are also crucial, by dealing and being responsible for large amounts of heterogeneous data in multiple formats and from various providers, that can be public or private. Controlling and identify the access to this data is the key. For this purpose, it is necessary to create a system capable of authenticating, authorizing, and account the usage of these services. While services in a development phase can have authentication and authorization modules directly implemented in them, this is not an option for legacy services that cannot be modified. This thesis regards the issue of providing secure and interoperable authentication and authorization framework, associated with correct identity management and an accounting module, stating the difficulties faced and how to be addressed. These issues are approached by implementing the proposed methods in one of the GNSS Data and Products TCS services, that will serve as a study case. While authentication mechanisms have improved constantly over the years, with the addition of multiple authentication factors, there is still not a clear and defined way of how authentication should be done. New security threats are always showing up, and authentication systems need to adapt and improve while maintaining a balance between security and usability. Our goal is, therefore, to propose a system that can provide a good user experience allied to security, which can be used in the TCS services or other web services facing similar problems.
