如何用Firebase API W/O注销创建新用户？[副本]

Question

firebase.auth().createUserWithEmailAndPassword(email, password)

我知道一个解决这个问题的方法：

保存用户的电子邮件和密码到内存和创建后用户重新登录回到原来的用户，但它需要保存密码，我不喜欢它。

firebase.auth().createUserWithEmailAndPassword(email, password)
      .then(user => {
        // login back to main account
        firebase.auth().signInWithEmailAndPassword(current_user_email, current_user_password).then(original_user => {

          const userRef = firebase.database().ref().child(`users/${user.uid}`);
          userRef.set({
            ...

要添加新的Firebase用户而不自动切换到该用户，可以使用辅助Firebase实例来创建该用户。例如：

var firebaseConfig = {
  apiKey: "asdasdlkasjdlkadsj",
  authDomain: "asdfg-12345.firebaseapp.com",
  databaseURL: "https://asdfg-12345.firebaseio.com",
  storageBucket: "asdfg-12345.appspot.com",
};

firebase.initializeApp(firebaseConfig);  // Intialise "firebase"
var fbAdmin = firebase.initializeApp(firebaseConfig, "Secondary"); // Intialise "fbAdmin" as instance named "Secondary".

创建用户：

fbAdmin.auth().createUserWithEmailAndPassword(email, password)
 .then(function(newUser) {
  // Success. 
  // Log out.
  fbAdmin.auth().signOut()
   .then(function () {
    // Sign-out successful.
    console.log('fbAdmin signed out.');
  }, function (error) {
    // An error happened.
    console.log('Error siging out of fbAdmin.');
    console.log(error);
  });
}, function (error) {
  // There's a problem here.
  console.log(error.code);
  console.log(error.message);
})

以上是针对普通JavaScript的。如果您使用自动配置来管理多个环境，这就有点棘手了。（另请参见保留URL）。
