问题描述

大家好，

我们有一个使用的Office 365环境
多重身份验证。当用户键入其用户名和密码到SharePoint在线站点时，还会向他们发送带有附加密码的文本消息。

我要做的是编写一个连接到SharePoint在线环境的C＃Windows桌面应用程序，使用
多重身份验证。



有人可以发送网站网址或C＃代码来演示如何使用
<创建一个简单的Windows桌面应用程序span name ="x_x_x_x_subject">多重身份验证。

我希望你能提供帮助！

解决方案

设置多个对用户进行因子身份验证，构建
  ClientContext以连接到SharePoint Online网站时，如果我们仍然将用户名+密码传递给SharePointOnlineCredentials对象，则会出现这样的错误消息：

因此，我们需要将用户名+应用程序密码传递给SharePointOnlineCredentials对象。

"应用程序密码，是在Azure门户中创建的密码，允许用户绕过多因素身份验证并继续使用他们的申请"。

Hi All,

We have an Office 365 environment that uses Multi-Factor Authentication. When a user types in their username and password to the SharePoint online site, they are also sent a text message with an additional password.

What I am trying to do is write a C# Windows desktop application that connects to the SharePoint online environment using the Multi-Factor Authentication.

Can someone please send either a website url or C# code that demonstrates how to create a simple Windows desktop application that uses Multi-Factor Authentication.

I hope you can help !

Hi,

After set up multi-factor authentication for an user, when constructing  ClientContext to connect to SharePoint Online site, if we still pass the username + password to SharePointOnlineCredentials object, there will be an error message thrown like this:

Thus, we will need to pass the username + App Password to SharePointOnlineCredentials object instead.

"An app password, is a password that is created within the Azure portal that allows the user to by-pass the multi-factor authentication and continue to use their application".

More information about App Password in multi-factor authentication:
