LoginApp Controller

Introduction

The LoginApp Controller facilitates secure integration between third-party backend services and our authentication system through a specialized OAuth flow. This controller is designed specifically for server-to-server authentication scenarios where direct user interaction is not required. The authentication process follows three key steps:

1. A third-party backend service makes a signed request to initiate the process
2. The service can then request a one-time authorization code using the provided state parameter
3. The standard OAuth flow proceeds to complete the authentication

This integration method is particularly useful for CMS systems like Typo3 and other backend services requiring secure authentication with our system.
