问题 Bear with me I am new to Google Firebase, sorry for my stupidity According to the JS Auth documentation on the Firebase website, it only shows how to get the displayName and how to update displayName. So I tried to update it. But it is sort of not logical, because how can you update something without creating it. So my question here is, how can I set displayName of user during registeration? function createUser(email, password) { firebase.auth().createUserWithEmailAndPassword(email, password)

I'd like my application to autheticate users and check what their role is; so I used the method signInWithEmailAndPassword coming from the object FirebaseAuth.getInstance() to log. Then I thought to save for each user a claim so I could keep track of their roles and to do this I use the Firebase admin SDK; problem is I no longer have the method signInWithEmailAndPassword on the class FirebaseAuth so I can't log my users.
