I went to login to my admin account a couple of days after installing and it said "undefined". I tried to reset my password and it said I could not use it. I had never used it before. I have check several other accounts on this website and it was the same.
I went to WP Security Contact page and filled out the contact form. That was two days ago and I have not heard a thing so I just uninstalled it.
All of my accounts are still broke though. I have had to reset the passwords manually to get them to work.
