I just checked multiple email addresses that I have used over many years and its findings accurately found webhosts where I had submitted my email addresses and were subsequently hacked. This did, of course, include Comcast. Shameful. HIBP reports also included collections of hacked email addresses that flat around the Dark Web.
I initially was uncomfortable entering my email addresses on another unknown (to me) website, but this outfit seems genuine. But now, once my email addresses are out there in the wild, there is not much you can do.

I am grateful to be told I have been pwnd having registered only a few months. However the company named is one I have had no dealings with. Whilst searching through the internet last year researching cars I may have clicked into this companies but certainly not set up a password so the advice to change my password for the offending company is not relevant.
I’m surprised HIBP doesn’t get more 5-stars : It provides an excellent service for free. I’ve been using it for years to monitor my own email and the ones from my family, it reminds them to change their passwords regularly (each time their email appears in a leak) and to develop good habits.
I made up several crazy test email addresses and it said they all have been compromised. And of course they suggest I get a strong password manager and they happen to have a good I can just click on. It's a site to sell product, not a real service for checking data breaches.

Have I Been Pwned (HIBP) is an online service that allows individuals and organisations to check whether their personal data has been compromised in known data breaches. Founded in December 2013 by Australian cybersecurity expert and Microsoft Regional Director, Troy Hunt, HIBP has become one of the most trusted resources for breach awareness and security education worldwide. The service aggregates billions of records from publicly disclosed breaches and provides a simple way for individuals and businesses to search for their email addresses or domains to see if they appear in any incidents.
Trustworthiness has been central to HIBP’s reputation. It has always operated with transparency, openly documenting breach sources, handling sensitive data responsibly, and offering services like domain verification so organisations can monitor corporate email addresses securely. Its partnerships with law enforcement agencies, including the FBI, and major technology companies such as Mozilla (for Firefox Monitor) further reinforce its credibility.
Over the years, HIBP has expanded to include features like password exposure checks (Pwned Passwords) and API integrations for developers and security teams. Its mission remains the same: to make breach data accessible in a responsible way, helping people understand and mitigate risks after a security incident.See more
