Auth setup with Neon, Keycloak and Koyeb

This guide outlines the process of setting up Keycloak, an open-source identity and access management solution, with Neon's Postgres database and deploying it on Koyeb. The steps include creating a dedicated Keycloak database in Neon, configuring a Keycloak database user, deploying Keycloak on Koyeb with SSL certificates, creating a Keycloak realm and client, and connecting a Next.js application to Keycloak for user authentication. The repository associated with this blog post provides an example of a Next.js application that integrates with Keycloak using NextAuth.js.
