After being announced some months ago and an internal/private beta program, support for Multi Factor Authentication for Office client is now available in public preview.

MFA support for Office client means if you are using the MFA feature available through Office 365 to secure access to your Office 365 tenant (or the Azure MFA to secure access to both online and on premises application) – see http://blog.hametbenoit.info/Lists/Posts/Post.aspx?ID=618 and http://blog.hametbenoit.info/Lists/Posts/Post.aspx?ID=556 to know more, you will no longer need to setup the app password to connect when using your Office client Smile

I recommend you read the following pages as there are some limitations to get MFA for Office client working.
