即使创建了用户，解析保存密码也不起作用

Question

所以我是新手解析，我正在尝试实现一个简单的登录功能。

我正在使用此代码

 ParseUser newUser = new ParseUser();
                newUser.setUsername(userName);
                newUser.setPassword(passwordFirst);
                newUser.signUpInBackground(new SignUpCallback() {
                    @Override
                    public void done(com.parse.ParseException e) {
                    if (e == null) {
                    AppUtils.toast(getApplicationContext(),"SUCCESS");
                    finish();
                    } else {
                    AppUtils.log(e.toString());


                    }
                }

                });

此代码确实创建了我可以在浏览器上看到的用户，但它没有保存密码，因此我永远无法登录。可能是什么问题？有什么建议吗？

正如我所说，用户是在浏览器中创建的，但密码字段仍未定义（未编辑），因此我无法登录。

感谢。
