你好，

您的问题很明确，但没有详细信息.您需要指出如何创建代码，并在可能的情况下提供少量代码示例(请确保使用代码按钮).还要详细说明其他人无法使用"的含义. 这可能意味着很多事情，包括无法连接到远程数据库.

Your question is clear yet the details are not there. You need to indicate how you created code and if possible supply a small sample of code (make sure to use the code button). Also explain in detail what you mean by "other people cant use it" which could mean many things including not being able to connect to a remote database.

高级别，登录名应该显示一个对话框，提示输入用户名和密码，搜索后端(我假设您是数据库，但您没有告诉我们)，允许三次登录，如果失败提供一种重置密码的方法， 将他们指向注册屏幕或与管理员联系，因为这是常见的地方.

High level, a login should present a dialog, prompt for username and password, search the backend (I assume in your case the database but you didn't tell us this), allow for three chances at login in and if fails either provide a method to reset the password, point them to a register screen or contact the admin as this is what is common place.

因此，请详细说明您如何创建登录名，并具体说明问题所在，多词多于少词.

So please explain in detail how you created the login and very specifically what is the problem, more words are better than few words.
