hotmail with 2-factor authentication not working again?

A couple of weeks ago, WebMail Notifier stopped checking my hotmail account again.  I have added and removed the account and completely removed and re-added WeMail Notifier, but I can't get it to check hotmail.  I'm using 2-factor authentication, but I'm never prompted for my code like I am with my Gmail account.  I was on 3.5.21, but backed off to 3.5.20 hoping it would help.  It didn't.
