This website (with a terrible name) is incredibly useful. I think it might be the best thing that I’ve seen on the internet so far, at least for today (and the day has just begun).
I’m pretty good with passwords so I keep on top of all of the data breaches that I hear about and that I’m aware of.
But, I know that my wife is not as aware of these things and doesn’t proactively change passwords systematically as I do. So, testing my wife’s email address reminded me of some accounts that I need to fix for her.
Might be worth doing for you and your family.
