That's true. My point was just that the important thing here is knowing personally which domains were affected so one can personally change those sets of credentials. If I don't know which of my credentials leaked then there's no value to me.

I was able to finally get access and did change the specific credential that had leaked (again, not assigning blame to any specific site here).

I don't understand how to find out which specific sites had my data leaked. Without that I can't take any action. I'm subscribed to email alerts but the alert did not include any details like the article said it would.
