You’ve probably heard terms such as authentication, authorization, OAuth2, OIDC, WebAuthn, but maybe you don’t have a good idea of exactly what they are or when they’re used. Authentication is a key technology that underpins large portions of the online world, and so it’s worth exploring in a bit more detail. In this episode of the Full Stack Journey podcast, Scott talks with Dan Moore of FusionAuth about all things authentication. We discuss * What is authentication? * What kinds or types of authentication are there out there? * What are some of the considerations around authentication? * What is OAuth2? What’s OIDC? * What is WebAuthn? * What are some related technologies?
