The idea is to enhance the security of OutSystems' exposed REST services by adding native support for OAuth2 authentication. This addition will enable developers to implement a robust and standardized authentication method, elevating the security posture of applications built on the OutSystems platform. 

Currently, OutSystems offers Basic authentication or custom authentication for exposed REST services, but native support for OAuth2 is absent. By incorporating OAuth2 into the OutSystems platform, developers can use a industry standard  authentication protocol.
