How To Check If Your Email Is in a Data Breach (Free)
A simple guide to checking whether your email address has been exposed in a data breach — and what it means if it has.
Over 15 billion credentials are currently circulating on dark web marketplaces. The chances are high that your email has appeared in at least one data breach — most people just don't know it.
What Is a Data Breach?
A data breach happens when hackers gain unauthorised access to a company's database and steal user information — typically usernames, email addresses, passwords, and sometimes financial data.

What Does It Mean If My Email Is Exposed?
It depends on what data was included in the breach:
- Email only: Low risk. Expect more spam.
- Email + password: High risk. Change that password everywhere you used it.
- Email + financial data: Critical. Contact your bank and credit agencies.
