Build a Secure OAuth 2.1 Login with Go, Keycloak, & MariaDB (PKCE Included)

We’ve covered the theory and seen the flow—now it’s time to code. In this final part of our OAuth 2.1 series, we build a production-ready authentication service from scratch using Go. No "black box" libraries, just clean code and deep security.

🚀 What we are building:
A Go backend integrated with Keycloak.
PKCE implementation (State, Verifier, and Challenge logic).
Persistent user storage in MariaDB.
Ephemeral session management with MongoDB.
Secure, HttpOnly cookie handling for the Dashboard.
