Safe and Sound – Firebase Authentication

"A ship is always safe at the shore - but that is not what it is built for."

- Albert Einstein

The previous chapter was extensive practice in a different way that you can save data in the cloud. However, securing data is an essential process. In this chapter, we will explore Firebase Authentication, which is designed to build a secure authentication framework while enhancing the sign-in and onboarding experience for end users. It gives an end-to-end authentication solution, supporting email and passwords; telephone authentication; and Google, Twitter, Facebook, and GitHub login. FirebaseUI gives us an adaptable, open source, drop-in auth feature that handles the UI flows for signing in. The FirebaseUI Auth fulfills best practices for validation on mobile and web applications, which can improve sign-in and sign-up rates for your application. As it is developed by the same group of developers that created Google Sign-in, Smart Lock, and Chrome Password Manager, Firebase security applies Google's internal skills in overseeing one of the most significant account databases in the tech world. It can take a long time to set up your own particular auth framework, and it requires an engineering team to keep that framework running into the foreseeable future. With this, you can set up the whole Authentication system of your application in less than ten lines of code, notwithstanding complex cases such as account combination.

Firebase Authentication gives backend services simple-to-utilize SDKs and instant UI libraries to authorize users to your application.

In this chapter, let's explore the following topics:

• Overview of Firebase Authentication
• Setting up the development environment for Firebase Authentication
• Firebase Authentication and functionalities
• Firebase AuthUI for authentication
• Managing onboard users
• Firebase for Auth providers
• Anonymous Authentication

The following section is an extensive look at Firebase Authentication, covering the Firebase UI and Firebase SDK to integrate Authentication into your applications. It's time to explore Firebase authentication.
