使用Identity2创建了一个mvc5应用程序，如何设置它以使用会话cookie，因此当浏览器关闭时它们会过期

使用Google登录名创建了一个Identity2的mvc5应用程序（几乎是空的应用程序，并且已启用了Google的功能）

我如何设置它以使用会话cookie，以便它们在浏览器关闭时过期。该应用程序将由可能会互换座位的学生使用，因此我需要登录名在浏览器关闭时到期。

我读了一篇SO文章，暗示这是默认设置，但是当我关闭浏览器并返回该站点时，它会记住Google登录信息。

抱歉让所有人破灭，但这不是重复的。

更改了假定的“答案”中的设置后，它在Chrome中得以重现，并且还可以在IE中得以重现。这是Asp.net Identity 2 + Google登录问题，而不是Chrome问题。

编辑我要解决的用例是，由于我们的应用程序在教室中使用，该学生A关闭浏览器而不是注销，然后下一个用户尝试登录。按现状，它们将自动登录到用户A的帐户中。

当重定向到登录页面时，我还想办法100％注销用户，但是我尝试过的所有方法都行不通。
