java - 使用 3 个 identfires 登录到 Firebase（用户 ID 编号 + 电子邮件 + 密码）

Question

我正在为我的工作公司构建一个项目，我希望它是私人登录，因此只有属于我们公司并具有唯一工作标识符号的员工才能登录和登录。

我昨天添加了这个问题，但现在我正在创建更清晰的问题并添加我的代码，因为我无法编辑前一个问题。

这个想法是做一个firebase检查用户是否有一个有效的ID和电子邮件和密码，如果ID号不是我们公司的ID号之一，即使电子邮件和密码是正确的，也会拒绝登录。

我需要它是私人的，这取决于我们的工作号码，通常是 6 位数。问候。

这是一些代码

我昨天发布了同样的问题，彼得（彼得哈达德）试图帮助我（感谢他），现在我发布了一个更好的版本。
