This guide explains how to integrate Firebase with OAuth2 Proxy in a Kubernetes environment for hybrid authentication.
Firebase Authentication is commonly used for user management, while Okta provides identity management and authentication solutions.
OAuth2 Proxy acts as an authentication gateway, intercepting requests and ensuring authentication via an OAuth provider before granting access.
The integration involves configuring Okta as an identity provider, deploying OAuth2 Proxy in Kubernetes, exposing OAuth2 Proxy with Kubernetes Ingress, and leveraging the Firebase Admin SDK for token exchange.
