Firebase Authentication Support in Android after a device reboots and before the user enters the PIN

## What feature would you like to see?

When the Android lock screen PIN is enabled, immediately after a device reboots and before the user enters the PIN, the Firebase Authentication module becomes unusable and returns an error. In a previous discussion with Google, we were informed that Firebase Authentication is not supported until the user enters the PIN. This limitation affects our ability to interface with Firebase. This limitation from Google is impacting all our major customers who have enabled the Android lock screen PIN for users.

The request is to add support for Firebase Authentication in Firebase Android SDK in User PIN mode even before the user enters the PIN on reboot on Android as high urgency.

## How would you use it?

The feature will enable us to use to authenticate with Firebase and interface Firebase Database such as Firestore to report device status to cloud and listen for the database changes form the other devices using Firebase SDK without needing looking for an alternative Cloud or tools.
