Check if Your Email Has Been in a Data Breach

The Problem

You don't know if your accounts have been compromised. Breaches happen constantly.

The Hack

Go to haveibeenpwned.com. Enter your email address. It shows which data breaches included your email and what data was exposed.

Why It Works

HaveIBeenPwned is run by security researcher Troy Hunt and aggregates billions of leaked records. If your email appears, change passwords on those sites immediately.

Pro Tips

• The site is trusted and used by security professionals worldwide
• If found in a breach: change that password AND any site using the same password
• This is why password reuse is dangerous — one breach exposes all accounts
• Check every 6 months
