A couple of years ago, in the SubSim
PC Hardware/Software forum, I posted a link to a free service offered by Firefox for finding out if your particular email address has been compromised in a data breach; you don't have to be a Firefox user to use the service; you simply input your email address(es) and the service scans for any mention of that address in any known data breach(es); I thought reposting the link might be of some use in regards to this topic...
Firefox Monitor:
https://monitor.firefox.com/
This is the link to the underlying service used by Firefox for its Monitor; if you wish, you can go directly to this link and search your address(es); this link does give a bit more detail on the breaches, if any, associated with your email address...
