退出Chrome时，身份验证将被清除。

Note however, that by default Chrome is running apps in the background, so it may not really exit even if you close all Chrome windows. You can either change this behavior under advanced setting, or e.g. under Windows, you can completely exit Chrome by using the Chrome icon in the systray. There should be an icon if Chrome is still running, but maybe you'll find it only in the popup with the hidden icons. The context menu of the Chrome icon has an entry to completely exit Chrome, and you can also change the setting for running apps in the background using that menu.

在Chrome中还没有办法做到这一点(Chrome 58)

我发现最好的解决方案是在隐身窗口中打开url，这将迫使您重新输入基本的身份验证凭据。

当您想要更改凭证时，请关闭隐身窗口并启动另一个隐身窗口。

你可以打开一个隐身窗口Ctrl+Shift+n每次你做一个测试。隐身窗口将不记得您上次输入的用户名和密码。

要使用这个技巧，请确保关闭所有隐身窗口。所有隐身窗口共享相同的缓存。换句话说，你不能打开多个独立的隐身窗口。如果您登录其中一个窗口并打开另一个窗口，这两个窗口是相关的，您将看到新窗口记住了第一个窗口中的身份验证信息。
