Working through the chapter and the given references, you have worked through many aspects and practical examples of the most important authentication protocols. We have tried to provide you with a very crisp reference card with much valid additional information about this topic. You should be able to use WS-Federation, SAML, OAuth 2.0, and OIDC in your design or configuration work for customers or your own organization. As already mentioned at the beginning of the chapter, we will use the knowledge in the upcoming chapters.
In the next Chapter 7, Deploying Solutions on Azure AD and ADFS, we start to work on it directly!
