Authentication for Svelte & SvelteKit

Syllabus

1. The Basics of Authentication

   We'll start with a bit of theory, looking into what authentication is, what the options are to implement authentication in web apps and what the relevant security aspects are to keep in mind.

2. The Demo Project

   We continue by setting up a demo project we'll be using throughout the workshop to set up a full authentication system.

3. Username & Password

   We'll build basic authentiation via a username and password first as a simple and straight forward means for users to login.

4. OAuth

   Next, we'll move to OAuth, which most real-world applications are likely to use. We'll look into the theory behind the approach and implement authentication via an OAuth provider in the demo project.

5. Application Concerns

   We end by looking into application concerns around authentication like deciding whether a user is currently logged in, and rendering the according UI, seamlessly moving the authentication state between the browser and the server side of a SvelteKit application, or persisting the authentication state beyond refreshs.
