How To Stop the Password Changed Email

Hi there

I’m using coupon classic theme and tried out the facebook social login this morning. It worked fine but I noticed a few admin emails came through that are superfluous. The first one was to me personally to click a link to update my password. Is it possible to edit this email somewhere as there are 2 links together with one space in between and I’d like to reformat the email if possible so it has a sign off and sounds more professional.

Once I followed that process to update my email, support receive an email saying password changed for user: my name. Where can I go to stop that email being sent please? I really don’t want to receive an email every time someone changes their password…
