Python FirebaseUI for User Authentication

[Pat Ng]

Follow https://firebase.google.com/docs/functions/get-started?gen=2nd#python_1 

as blueprint for building a web app. 

Next, add Firebase user authentication FirebaseUI, 

https://firebase.google.com/docs/auth/web/firebaseui

While using <script> tag works, a concern is that Firebase credentials are exposed in <script> tag.

Q:  is there Firebase documentation on / example of using python with prebuilt sign-in options FirebaseUI (Google, email, etc.)?

Much appreciated your comments and pointers.
