Common questions
Is this breach checker actually free?
Yes, completely free with no account or sign-up required. You can check as many email addresses as you need.
Do you store the email address I enter?
No. Your email is used only to run the check and isn't retained afterward. We never ask for or see your password.
What should I do if my email is found in a breach?
Change the password on the exposed account and anywhere else you reused it, enable two-factor authentication, and use a password manager going forward so no password is ever reused again.
Where does this tool's breach data come from?
It checks against databases of publicly known breaches compiled from breach-notification filings, security research, and confirmed incident disclosures.
Should I check more than once?
Yes — new breaches are discovered constantly, so an email that's clean today can appear in a newly disclosed breach next month.
