Unable to authenticate to SharePoint Online with an account using MFA.
原因
--TargetPass parameter included in the migration command.
解决办法
--TargetPass must be empty and --TargetOAuth must be included in the command.
NOTE: If the password is empty and OAuth is not enabled, the default (currently logged in Windows user) credentials will be used. If OAuth is enabled, interactive (OAuth) login credentials will be used.
