有没有一种方法可以让我的GUI密码管理器使用Python中的用户名和密码进行访问？

我使用Python制作了一个程序（密码管理器），我可以输入网站、电子邮件和密码，然后单击“添加”按钮将输入写入json文件，我对此没有问题，它工作正常，我想做的是，当我打开程序时，我想让它询问我的登录用户名和密码

更不用说，我已经创建了登录窗口，其中有两个标签，每个“用户名”和“密码”有两个条目，并且在下面添加了一个“回车”按钮，我还在第107行创建了一个名为“验证”的函数，并使用“command=validate”将其分配给“回车”按钮，我想不出一种方法来计算username.input.get（）=“username”和password.input.get（）=“password”我的程序何时应该打开，这个登录窗口何时应该关闭

我已经搜索了很多，但我找不到任何可以在我的代码中使用的东西

这是我的密码：

您可以隐藏登录窗口，添加

password\u checker\u window.destroy（）

并将所有manager内容放入一个函数中，然后在验证登录后调用它，但这会产生另一个问题。密码管理器的变量现在是局部变量，因此如果没有大量全局变量，就无法从函数中访问它们。
为了解决这个问题，我将您的程序重新组织为两个类。这些函数已组织到它们的相关类中，现在可以访问变量。要了解有关类和tkinter的更多信息，请搜索“OOP tkinter”（它使大型程序更易于使用）。
我还修复了密码生成器的一个小错误，在插入新密码并添加到所有小部件的父级之前，旧密码不会被删除。

虽然这一切现在都起作用了，但我想看看Serge Ballesta评论中提到的一些安全措施，因为您的密码管理器目前非常不安全

常见的方法是在一些持久性存储（这里可能是您的json文件）中设置密码哈希。在密码被验证之前，你应该一直被屏蔽在屏幕上。但是如果您想要最低限度的安全性，那么所有密码（或所有其他数据）都应该加密，并且应该使用用户密码（直接或不直接）来解密它们。还有一些工作…使用类的原因之一是为了摆脱

global

，避免使用它。
