Create an account without logging in

Question

I'm developing an app where certain users can create accounts for other users by inserting an e-mail, password and role (admin, editor, etc..). My initial idea was not like this so my code does not what I want. Right now, anytime I create an account, that same user logs in with the data from this new account. What I want to do is just write on firebase realtime database the data from the new account. Can you help me?

Here is my class
