Frequently asked questions about the data breach checker
Find out if your private information has leaked in data breaches with F-Secure’s free data breach checker. Type in your email address and let the tool search for breaches.
If your email is hacked, immediately change your password to something strong and unique and log out of all active devices.

If you want to know if you have been hacked, type in your email address in F‑Secure’s data breach checker and see if your personal information has been compromised.
The tool searches a massive database of known data breaches and dark web leaks to see whether personal information associated with your email appears in any of them.

Yes, this checker is safe to use. F‑Secure does not store your email address or any breach information discovered during the search. For your privacy, the specific details of the leaks are sent only to the email address being checked, rather than displayed publicly on the website.
Identity theft refers to a situation in which someone uses another person’s personal information to carry out unauthorized activities, such as fraud, making purchases, or entering into loan agreements. Criminals can obtain your data through physical theft, public access to information, or data breaches. The best way to protect your identity online is to use strong passwords, two-factor authentication, an authentication key, and be careful what you share across different online services.
A data breach occurs when a hacker gains access to the database of a service or company that contains users’ private information. This information can range from usernames and passwords to social security numbers, addresses and even payment details. These lists are then usually sold online to criminal groups that seek to profit from this information.
It means one, some or all of your card details appeared in a known data breach. The tool flags any card data that has been exposed — whether that’s partial or complete information — because even partial card data can still be useful to criminals.
Fraudsters frequently combine pieces of information from multiple breaches — card digits from one leak, a name and address from another — to build a picture that’s detailed enough to commit fraud.
If your credit card has been breached, contact your card issuer to let them know and request a replacement card, check your recent statements for any transactions you don’t recognize, and turn on transaction alerts if you haven't already.
