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.
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.
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.
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.
