It's possible to have multiple Firebase instance in your apps

FirebaseOptions options = new FirebaseOptions.Builder()
   .setApplicationId("Your AppId") // Required for Analytics.
   .setApiKey("You ApiKey") // Required for Auth.
   .setDatabaseUrl("Your DB Url") // If you wanted to
   .build();

FirebaseApp.initializeApp(context, options, "CompanyA");

Which you can get Firebase instances by

FirebaseApp appCompanyA = FirebaseApp.getInstance("CompanyA");

You can see the full example use of Auth and Realtime Database using multiple Firebase instance here

I'll leave this solution here which may duplicate with another answers for someone who might need this
