你所需要做的就是在地址栏中输入chrome://restart, chrome和所有在后台运行的应用程序将重新启动，Auth密码缓存将被清理。

对于Chrome 66，我在下面找到了相关选项:

右上…菜单->更多工具->清除浏览数据 点击“高级”页签 勾选“密码”框(取消你不想清除的密码) 按“清除资料”

使用一个新的隐身窗口可能更容易，但当你忘记并想要清除保存的密码时，这个方法不需要重新启动Chrome(这也有效)

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

这里有很多很棒的建议，我将给出我认为最有效的一个:

只要在网站上修改密码就可以了。旧的身份验证将变得过时，Chrome将再次请求它。

因为我有一个终端打开，我做了一个简单的脚本更改密码，在两次按键它是递增的。

正如@SalCelli提到的，chrome://restart工作。但是，这会重新启动所有的选项卡。

另一种方法是采用CEGRD建议的隐身模式

但是，如果你不喜欢在Chrome 86 (Mac)上重新启动和隐身使用，我发现@opsb和Mike提供的答案只适用于以下额外步骤。

Enter the wrong username in the url without the resources eg: if the url is http://mywebsite.com/resources/, it will not work if I enter http://wrong@mywebsite.com/resources/, but will work if I enter only http://wrong@mywebsite.com/ it clears the Basic Auth credentials prompt for the credentials again However, entering the valid credentials will not work, as in the background, chrome still send the wrong user as part of the url, even though the url appears right in the address bar When prompted for credentials you would need to Cancel, and click the address bar and reload the page from pressing enter. Now enter the correct password

按下组合键Ctrl+Shift+Delete 你会看到弹出在chrome 选中上述选项，然后单击“清除数据”，就完成了。
