What is We Leak Info?

We Leak Info is the world's fastest and largest data breach search engine. We help individuals secure themselves online by allowing them to verify if their password or email has been leaked. Unlike similar sites such as Have I Been Pwned, We Leak Info allows the user to view the raw results from the database.

We Leak Info is a freemium tool and provides free searches to everyone without registration. However, we require a small payment to view the raw results of a search. This goes towards maintaining expensive server fees and improving the service. Being the fastest data breach search engine on the market, each search takes a fraction of a milliseconds. We currently hold over 8 billion records.

Deleted Accounts

Out of the 150,633,047 accounts, we discovered that 77 accounts were deleted or disabled.


The hashes were encrypted using SHA1 with salts. The version we received did not have the salts, however we have altered the database and filled in the salt column with the correct salt to enable decrypting of the hashes.

Most of the hashes can easily be decrypted through our hash API.
