Yahoo mail log in and Windows Live Mail mystery

Hello all,

My father in law's Windows Live Mail began having troubles logging into his yahoo email account yesterday.

The typical authentication error appears below...

But this doesn't appear to be a simple password issue because he can log into this account through the web interface. I even had him change his password and then apply this password to the POP3/SMTP sections in the Windows Live email configuration.

All the Yahoo email settings were verified, at least, 4 times so it doesn't appear to be a settings issue. Additionally, his Live Mail program is successfully sending/receiving email from another Yahoo account, as well as GMAIL, and HotMail.

Saving the best for last...
This account was successfully phished yesterday! My father in law received a Yahoo'ish looking warning email telling him that his account was compromised. Unfortunately, he dutifully followed the instructions and gave these a-holes his password. I am only adding this to give you full details but I don't think this is the source of the problem because:
a) I had him change his password
b) He can log into his Yahoo email through the web interface

Any thoughts?

Thank you so much!

It turns out that he had secondary authorization turned on (accidental). This requires requesting a separate and temporary email password that is entered in place of the regular password inside the non-web app.

Done!

I was hoping that someone could provide some insight into this weird issue. I'm going over for a hands-on look tonight.

Maybe I'll look up a portable (doesn't require an installation) version of another email program... like Thunderbird.
