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.

打开Chrome菜单 选择设置 滚动到底部 单击“显示高级设置…” 滚动到底部 在“系统”下取消选中“当谷歌Chrome浏览器关闭时继续运行后台应用程序”的复选框

对于Windows 10:对我有用的是在凭据管理器中清除Windows凭据中的凭据。

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。

我用的是Chrome 75。我发现重新启动Chrome不起作用。但是重新启动Chrome浏览器并打开开发者工具就可以了。我不知道为什么会这样。
