我面临的问题是：
我开发了一个用户登录表单。但是，即使只有电子邮件部分输入错误，我也会收到消息“您的电子邮件地址和密码都不正确”。当电子邮件输入错误时，我想收到一条消息，表明只有电子邮件地址不正确。
我一直在等待的解决方案：
当电子邮件地址输入错误时，仅应向用户显示电子邮件地址不正确的错误消息。同样，如果密码输入错误，则仅显示密码错误消息。
发生的事件：
目前，即使只有电子邮件地址输入错误，也会显示“您的电子邮件地址和密码均不正确”的消息。
对于 2023 年 9 月以来创建的项目，Firebase 会自动启用“针对电子邮件枚举攻击的保护”。这会改变许多 API 的行为，包括您正在调用的 signInWithEmailAndPassword。具体来说，API 将不再返回
