How to do Multi-factor auth with SharePoint-Online CSOM

Jose Carrillo

Using just a password-based authentication, it's easy to authenticate in CSOM from my C# application:

context.Credentials = new SharePointOnlineCredentials(username, password);

But how to authenticate when Multi-factor authentication (MFA) is activated?

Since the MFA was activated in the tenant, i get the error:

The sign-in name or password does not match one in the Microsoft account system

Microsoft.SharePoint.Client.Idcrl.IdcrlAuth.GetServiceToken

Is there any way?

I´ve read about using APP PAssword, but the new password created doesn´t work from C# code

Thanks.
