Welcome back to another video! If you're watching this video, you've probably tried working with authentication before, whether it's adding it to an API, a website, or some other type of app, and you've probably seen how time-consuming and difficult it can be! Plus, doing it yourself from scratch can introduce a number of security risks and a whole host of problems you don't want to deal with. In this video, I'll show you the simplest authentication I've ever used, it's called Passage! I hope you learn something and enjoy the video!
