Has My Email Been Hacked? Free Breach Checker
Enter your email to instantly see if it's been exposed in a known data breach — which breaches, when they happened, and exactly what information was leaked.
Worried your email is already out there? You're probably right.
Here's the uncomfortable truth: if you've used the same email for a few years, it's almost certainly sitting in at least one breach — the only question is how many. And once your data leaks, it gets copied, sold, and traded on the dark web indefinitely. No free checker can pull it back. That's exactly what Aura is built for.

What to do if your email has been in a data breach
Finding your email in a breach isn't a disaster on its own — but it is a signal to act quickly. Work through these steps in order:
- 1
Change every reused password
Attackers take a leaked email-and-password pair and try it on dozens of other sites — a trick called credential stuffing. Change the breached password and any account that shared it. Use our password generator to create strong, unique ones, and the password strength checker to test them.
- 2
Turn on two-factor authentication (2FA)
Even if a password leaks, 2FA stops attackers from logging in without your second factor. Enable it everywhere it's offered — especially email, banking, and social accounts.
- 3
Watch for breach-themed phishing
After a breach, scammers send fake "secure your account" emails with malicious links. Before clicking anything, run it through our free link safety checker.
- 4
Freeze your credit and consider monitoring
If your SSN or financial details were exposed, a credit freeze blocks new-account fraud for free. For ongoing peace of mind, compare the best identity theft protection services.
- 5

Why do emails end up in data breaches?
A data breach happens when a company you have an account with is hacked and its user database is stolen — then often published or sold on the dark web. Because the average person has dozens of online accounts, a single email address accumulates exposure across many breaches over time. In fact, the latest data breach statistics show most people were notified of at least one breach in the past year.
Once leaked, your credentials fuel credential-stuffing attacks, targeted phishing, and account takeovers. Learn exactly how hackers steal passwords so you can shut down the most common attack paths.
How this email breach checker works
Enter your email and we check it in real time against a large database of known data breaches, then show you which breaches it appeared in, when they occurred, and the categories of data exposed. It's completely free and requires no sign-up.
Your privacy comes first: we never store the email you check, never log it in plaintext, and never add it to any mailing list automatically. The lookup runs server-side and your address is discarded the moment the result is returned.

Frequently Asked Questions
Everything you need to know about checking your email for data breaches.
Enter your email address in the checker above and click "Check My Email." We instantly compare it against a large database of known data breaches and show you exactly which breaches your address appeared in, when they happened, and what type of information was exposed — such as passwords, phone numbers, or physical addresses.
A data breach happens when a company or service you use is hacked and its user data is stolen — often ending up for sale on the dark web. If your email is in a breach, attackers may have your password, personal details, or enough information to attempt identity theft, phishing, or credential-stuffing attacks on your other accounts. Knowing which breaches you're in tells you exactly which passwords to change.
Yes. The email breach checker is 100% free with no sign-up required to run a check. Just enter your address and get an instant report of the breaches it appears in.
Take three steps immediately: (1) Change the password for the breached account and any other account that reuses that password. (2) Turn on two-factor authentication wherever possible. (3) Use a password manager so every account has a unique, strong password. Because breached data circulates on the dark web indefinitely, it's also worth using an identity-monitoring service that alerts you if your information resurfaces or is used to open accounts in your name.
We check your email against an aggregated database of publicly known data breaches — the same kind of breach corpus security researchers use. When available, we also show the breach date and the categories of data that were exposed so you can gauge how serious each one is.
No. We do not save the email addresses you check. Your address is used only to run the breach lookup in real time and is never stored in plaintext, logged, added to any mailing list automatically, or shared with third parties. If you choose to be notified about future breaches, that's a separate, explicit opt-in.
It varies by breach. Common exposed data includes email addresses, passwords (sometimes in plaintext, sometimes hashed), usernames, phone numbers, physical addresses, dates of birth, and — in the most serious cases — payment details or government ID numbers. The checker lists the specific data categories exposed in each breach your email appears in.
New breaches surface constantly, so it's smart to re-check every few months, and immediately after you hear that a service you use has been hacked. For continuous coverage, an identity-monitoring service watches for new exposures automatically and alerts you the moment your email appears in a fresh breach — so you don't have to remember to check.
