Here's a neutral and interesting summary of the provided text in one paragraph: This tutorial guides readers through securing a GoLang program with OAuth using FusionAuth as the authentication provider. The process involves setting up the FusionAuth server, configuring the GoLang program to redirect users to a login form, and making use of an access token to fetch user data via OIDC. The tutorial covers the installation of FusionAuth, creating a new application, setting up the development environment for GoLang, and implementing OAuth authentication with handlers for displaying a login page, handling callbacks, and fetching user information. By following this tutorial, developers can secure their applications using any OAuth-compatible identity provider and make requests to other APIs while presenting an access token as a credential.
