HAVE I BEEN PWNED

Have I Been Pwned is a free data breach search and notification service that monitors security breaches and password leaks for users' security. The service has been used by tens of millions of people to search through billions of breached records and supports tens of thousands of visitors a day. They aggregate data that's been exposed publicly and enable individuals and organisations to assess their exposure. Searches only require an email address and provide immediate feedback. The notification service monitors for ongoing exposure and emails an address owner if it subsequently turns up in a data breach.
