I know how to remove registered users manually via web interface (which is also answered by this question). This can be done without providing user's password.
Is there a way to remove a user automatically without their password? I have only found removeUser API call which requires user's password.
It would help to simplify deployment for testing/stage environments.
There is no API to programmatically access the email/password users in Firebase.
For development purposes, you can delete them through the Login & Auth tab of your app's dashboard.
