Cit0day - is it possible to include the site(s) whose lists an email appeared in?
In the alert email for the Cit0day breach, the only information provided is that one's email appeared somewhere in the breach of the 23k websites. If it's possible, it could be helpful for users to be informed of which specific site(s) their credentials were listed under.
I fully grant the larger point about encouraging the use of a password manager to mitigate the risk regardless. Thanks! :)
HIBP only matches an email address to a single “breach” (which is what the Cit0day collection is treated as) and doesn’t have a provision to add any additional data such as which file the email address appeared in.
