Email Breach Checker
Check if your email address has appeared in known data breaches. We use the HaveIBeenPwned API — the industry standard trusted by governments and Fortune 500 companies.
Your email is sent to the HaveIBeenPwned API for lookup. It is not stored by us.
If your email was breached, your friends and family are probably affected too. Help them check.
Frequently Asked Questions
What is a data breach?
A data breach occurs when unauthorized individuals gain access to confidential data from a company's systems. This can expose email addresses, passwords, phone numbers, addresses, and other personal information.
Is it safe to enter my email?
Yes. We send your email to the HaveIBeenPwned API, the industry standard for breach checking used by governments and major companies. We do not store, log, or track any emails entered into this tool.
What should I do if my email was breached?
Immediately change your password on the affected service. Enable two-factor authentication (2FA). Use unique passwords for every account. Consider using a password manager. If financial data was exposed, monitor your accounts and consider a credit freeze.
How does HaveIBeenPwned work?
HaveIBeenPwned (HIBP) is a service created by security researcher Troy Hunt. It aggregates data from known breaches and allows people to check if their information was exposed. It's trusted by governments and used by organizations worldwide.
Can I check someone else's email?
Yes — this is a public lookup tool, the same data anyone can access through HaveIBeenPwned. If someone you know has been affected, encourage them to change their passwords and enable 2FA.
Why does it say "no breaches found" when I know I was breached?
Not all breaches are reported or loaded into the HIBP database. Some breaches are private, some are still being processed, and some may not include your specific email. A clean result doesn't guarantee you haven't been breached — it means your email wasn't found in currently known breaches.
