This tutorial provides step-by-step instructions on how to implement Log in with GitHub functionality in an app using Go and WorkOS. The process involves installing the WorkOS Go SDK, setting secrets, configuring a GitHub connection, providing client credentials to WorkOS, configuring a redirect URI, and setting up the frontend and backend. The tutorial covers both cases where AuthKit is used and when building a custom login box. It also provides resources for further learning on handling user sessions, implementing logout, adding SAML SSO, access control, provisioning users automatically, and more.
