Building your own authentication system can be a difficult and time-consuming task. Using existing platforms to handle your authentication flow for you will save you a lot of time and doesn’t even have to cost you any money. The free plan of Firebase, one of the most popular platforms than can handle authentication for you, allows any developer to quickly build secure authentication systems easily. It helps you build applications fast, without managing infrastructure. In this tutorial, we are going to use this platform to quickly implement our own authentication flow. We will do this using Next.js, Typescript, and TailwindCSS.
To follow along, you should have an existing project. You can follow these other tutorials on Better Programming to set your project up:
