Data Breach Check

Check if your email address has been exposed in known data breaches. We search breach databases to find out if your accounts have been compromised.

What is a Data Breach?

A data breach occurs when sensitive, protected, or confidential data is accessed, disclosed, or stolen by an unauthorized individual. Email addresses and passwords are among the most commonly compromised data.

What to Do If You're Breached

• Change your password immediately: Use a strong, unique password for each account.
• Enable two-factor authentication (2FA): Add an extra layer of security to your accounts.
• Check other accounts: If you reused the same password, change it everywhere.
• Monitor for suspicious activity: Watch for unusual login attempts or transactions.
• Use a password manager: Generate and store unique passwords for every service.

How Data Breach Checking Works

Our breach check service aggregates data from known breaches and allows anyone to check if their email has been compromised. The service does not store passwords — only email addresses and breach metadata are checked.

How does this tool work?

This tool checks your email address against known data breaches using the XposedOrNot API. When you enter an email, it queries a database of billions of compromised accounts from thousands of data breaches. If your email appears in any breach, it will show you which breaches exposed your data.

Your email is checked securely — only the email address is sent to the API, and no passwords are ever transmitted or stored. The service does not reveal the actual compromised passwords, only the names and details of the breaches.

Why should you check for data breaches?

• Account security: Find out if your email has been exposed in any known data breach.
• Password safety: If your email was breached, any passwords you reused across sites may be compromised.
• Identity protection: Early detection of breaches lets you take action before criminals exploit your data.
• Peace of mind: Regular checks help you stay on top of your digital security.

Common Types of Compromised Data

• Email addresses: The most commonly exposed data point.
• Passwords: Often stored as hashes, but weak hashes can be cracked.
• Personal information: Names, addresses, phone numbers, dates of birth.
• Financial data: Credit card numbers, bank account details.
• Social media data: Profile information, private messages.
