Update 20161108 - original answer below

Firebase just released its firebase-admin SDK, which allows server-side code for this and other common administrative use-cases. Read the installation instructions and then dive into the documentation on creating users.

original answer

This is currently not possible. Creating an Email+Password user automatically signs that new user in.

I got André's very clever workaround working in Objective-C using the Firebase iOS SDK:

NSString *plistPath = [[NSBundle mainBundle] pathForResource:@"GoogleService-Info" ofType:@"plist"];
FIROptions *secondaryAppOptions = [[FIROptions alloc] initWithContentsOfFile:plistPath];
[FIRApp configureWithName:@"Secondary" options:secondaryAppOptions];
FIRApp *secondaryApp = [FIRApp appNamed:@"Secondary"];
FIRAuth *secondaryAppAuth = [FIRAuth authWithApp:secondaryApp];

[secondaryAppAuth createUserWithEmail:user.email
                             password:user.password
                           completion:^(FIRUser * _Nullable user, NSError * _Nullable error) {
                                [secondaryAppAuth signOut:nil];
                          }];

If you are using Polymer and Firebase (polymerfire) see this answer: https://stackoverflow.com/a/46698801/1821603

Essentially you create a secondary <firebase-app> to handle the new user registration without affecting the current user.

Answer 4

On the web, this is due to unexpected behavior when you call createUserWithEmailAndPassword out of the registration context; e.g. inviting a new user to your app by creating a new user account.

Seems like, createUserWithEmailAndPassword method triggers a new refresh token and user cookies are updated too. (This side-effect is not documented)

Here is a workaround for Web SDK: After creating the new user;

firebase.auth().updateCurrentUser (loggedInUser.current)

provided that you initiate loggedInUser with the original user beforehand.

The Swift version:

FIRApp.configure()

// Creating a second app to create user without logging in
FIRApp.configure(withName: "CreatingUsersApp", options: FIRApp.defaultApp()!.options)

if let secondaryApp = FIRApp(named: "CreatingUsersApp") {
    let secondaryAppAuth = FIRAuth(app: secondaryApp)
    secondaryAppAuth?.createUser(...)
}

I faced the same problem, and I solved it with this way:

When the user login, I save the email and password in the shared preferences. And after creating the user, I login the user again with email and password that I have saved before.

    String currentEmail = MyApp.getSharedPreferences().getEmail();
    String currentPass = MyApp.getSharedPreferences().getPass();

    FirebaseAuth auth = FirebaseAuth.getInstance();
    auth.createUserWithEmailAndPassword(email, pass)
            .addOnCompleteListener(AddStudent.this, new OnCompleteListener<AuthResult>() {

                @Override
                public void onComplete(@NonNull final Task<AuthResult> task) {

                    if (task.isSuccessful()) {
                        String currentEmail = MyApp.getSharedPreferences().getEmail();
                        String currentPass = MyApp.getSharedPreferences().getPass();

                        //Sign in again
                        auth.signInWithEmailAndPassword(currentEmail, currentPass)
                                .addOnCompleteListener(AddStudent.this, new OnCompleteListener<AuthResult>() {
                                    @Override
                                    public void onComplete(@NonNull Task<AuthResult> task) {
                                        if (!task.isSuccessful()) {
                                            Log.e("RELOGIN", "FAILED");
                                        } else {
                                            Log.e("RELOGIN", "SUCCESS");
                                        }
                                    }
                                });

                        finish();
                    }
                }
    });
