Does Firebase need authentication?

Firebase gives you complete control over authentication by allowing you to authenticate users or devices using secure JSON Web Tokens (JWTs) . You generate these tokens on your server, pass them back to a client device, and then use them to authenticate via the signInWithCustomToken() method.

Data encryption Firebase services encrypt data in transit using HTTPS and logically isolate customer data.

You don’t have to use Firebase authentication in order to use FireBase Push Notifications, Invites, etc . That’s one of the beauties of Firebase; you can choose which service to use. Show activity on this post. You can save all users, and you can authenticate with Google, Facebook, only email.
