A whole slew of usernames and plaintext passwords were leaked for a number of different sites—at 772 million and 21 million respectively, it’s the largest data leak in history.
This collection of email address and passwords—dubbed “Collection #1”—groups together several smaller breaches into a larger master file of sorts. This huge collection of data comes from several different sites, so your personal info may have been compromised from multiple different sources. That means your information could’ve been compromised multiple times—the same email address with different passwords.

So, to find out if your email or passwords have been compromised with the Collection #1 leak—or any other before it—head over to Have I Been Pwned, enter your email address, and brace yourself for the results.
Even though there seems to be some discrepancy on the number of the login credential being leaked cited by different sites, it is in the region of one billion "more or less".
I found another site which, beside Have I been Pwned, lists some other resources as well:

My question is if you have used these services and do you find them legit and trustworthy?
