So I use Edge as my main browser and I just went to a site and Edge popped up a little thing saying "hey guess what, we found your login credentials for this site exposed on the Dork Web, you might wanna change that shizzle" and I was like "wow thank you Miss Edge, that's super-helpful" and then I clicked on the button on the prompt and it took me to an Edge settings flyout where it showed the leaked usernames and, when I re-entered my account PIN, the leaked passwords connected to those usernames. It also listed all of the sites that Edge knows of where I use those username/password combinations (I use Edge as my password manager).
This is a newish feature that was added to Edge just a few months ago; you can read more about it
here if you are interested.
