Summary
In this chapter, you learned how to use OAuth 2.0 to provide your applications, as well as third-party applications, with access to services without exposing credentials, as well as only giving applications exactly what access they need. You also learned how OpenID Connect can be leveraged for single sign-on to your applications, as well as allowing external users to access your applications. Finally, you learned how SAML 2.0 is still an important standard that you should be aware of, even though you may not want to choose it for your own applications.
In the next chapter, you will get a deeper understanding of OAuth 2.0 with a practical guide on how you can use Keycloak to leverage this standard in your applications.
