Website allowing internet users to check whether their credentials have been compromised in the past.

Have I Been Pwned? (HIBP) is a website that allows internet users to check if their personal data has been compromised by data breaches. The service collects and analyzes dozens of database dumps and pastes containing information about hundreds of millions of leaked accounts, and allows users to search for their own information by entering their username or email address. Users can also sign up to be notified if their email address appears in future dumps.
