Your email showed up in a breach. Here's what that means.
Have I Been Pwned (HIBP) is a trusted security tool that tracks data breaches. If your email appeared in their database, here's how to understand your risk and respond appropriately.
First: Check what was exposed
Not all breaches are equal. HIBP shows you exactly what data was compromised in each breach. If you haven't checked yet:
Is Have I Been Pwned trustworthy?
Yes. HIBP was created by Troy Hunt, a respected security researcher and Microsoft Regional Director. The site doesn't store your email—it just checks if your email hash matches known breach data. It's widely recommended by security professionals and even government agencies.

Prevent future exposure
Use a password manager
Generate and store unique passwords for every account. Popular options: 1Password, Bitwarden, Apple Keychain.
Use email aliases
Services like SimpleLogin, Firefox Relay, or Apple's Hide My Email let you create unique addresses for each service. If one gets breached, the others stay clean.
