Is money involved in this partnership? If so, who paid whom?
What was the motivation behind this? Is there any study that shows any benefit from haveibeenpwned.com? I.e. has there been a decrease in hijacked accounts, etc?
I don't think there's been studies, but it seems obvious to me that the goal here is to prevent re-use of leaked passwords, and I'd consider it a surprising result if this wouldn't help in that.
> When we first implemented the check, about 19% of logins were greeted with the message that their password was not safe enough. Today, this has dropped down to around 11-12% and hopefully will continue to go down.
