/ About /

Have I Been Pwned (HIBP) is a free service that lets individuals check whether their email address or password has appeared in known data breaches. It also offers breach notification alerts and a RESTful API for developers and organizations to programmatically query breach data. Organizations can verify domain ownership and retrieve all breached email addresses associated with their domain.

/ How it works /

Users enter their email address on the site or query the API, which checks it against a database of hundreds of known data breaches and returns any matches.

/ Who it's for /

Individuals concerned about their online security, developers, and organizations wanting to monitor breach exposure
