Have I Been Pwned

Check if your email or phone number has been in a known data breach.

Have I Been Pwned (HIBP) is a free and widely respected tool that lets individuals check if their email addresses, phone numbers, or passwords have been exposed in known data breaches. Created by security researcher Troy Hunt, HIBP aggregates data from hundreds of breaches and offers a simple, privacy-conscious interface to verify your exposure without revealing sensitive details. By checking your data against its extensive breach database, HIBP helps users take early action—such as changing passwords or enabling two-factor authentication—before attackers exploit the compromised information. No login is required, and your queries are not stored, making it a privacy-positive option compared to services that require account creation or email confirmation. HIBP also offers notifications, so users can be alerted to future breaches involving their data. It’s one of the most effective tools available for regaining control after a compromise and maintaining awareness of ongoing threats. Run by security expert Troy Hunt, this is one of the most trusted breach checkers available.
