They can still back out of the deal.

I have a yahoo mail account with a password I haven't used anywhere else. Not even similar. Should I be concerned about this?

You answered your own question. 

I would be more worried about any sensitive emails in your case. I just went through and changed the pw on any account with a card attached to it.
