Summary
In this chapter, we implemented the logic to allow users to authenticate themselves to our API server. We also used JSON web tokens to keep our application stateless; this is important when we want to scale your application, something which we will discuss in Chapter 18, Robust Infrastructure with Kubernetes.
However, it is important to remember that security is not an easy undertaking. What we've covered in this chapter is only a small part of the puzzle. You should view this chapter as a first step in securing your application, and always stay informed about the latest security holes and best practices.
In the next chapter, we will finish up our backend API by documenting our API using OpenAPI and Swagger.
