What is the best way to authenticate two types of users (Student and Driver) in my android app using Firebase [duplicate]

Answer 1

I don't know if there's an official or standard way to do this with Firebase but if that's not the case what I would do is to store the type of user in the database and then check the information before login. The logic would be the following:

1. Get the type of user given an email
2. Check if the type returned matches the login screen type
3. Do the login if the type matches, show some error otherwise

I hope this helps.
