so recently i have been receiving emails from blizzard saying "too many attempts warning" as the email header so me thinking these were phising emails i binned them.
anyway i go to log into my account and up pops "too many attempts warning".
so it seems someone is trying to brute-force my account needless to say i have now changed all my login details and have a authenticator anyway.
so if you get one of these emails its probably genuine but still go to your account yourself and not click any links.
