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.

Problem

People and organizations have no easy way to know if their email addresses or passwords have been compromised in data breaches.

For

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

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.
