Enterprise Authentication with Dex

Grab has implemented Dex as a federated OpenID Connect provider to centralize and standardize enterprise authentication across internal applications. This initiative aims to streamline access management, enhance developer velocity, and improve user experience by integrating various Identity Providers (IdPs) through OIDC. Key features include token exchange for secure service-to-service communication and a 'kill switch' mechanism for IdP outages to ensure service continuity. The next phase involves leveraging this foundation for a unified authorization model.
