Enter your email address and click check. The tool searches breach databases and reports which breaches (if any) contain your email. Results show the breach name, date, compromised data types, and recommended actions.
Immediately change the password for the breached service. If you used the same password elsewhere, change those too. Enable two-factor authentication (2FA) on all important accounts. Monitor your accounts for suspicious activity.
Yes. Reputable breach checkers only check if your email exists in known breach databases. They do not store your email or share it with third parties. The check is performed securely.
Breaches occur through: exploiting software vulnerabilities, SQL injection attacks, phishing employees, misconfigured databases, insider threats, and third-party vendor compromises. Even major companies like LinkedIn, Adobe, and Yahoo have suffered breaches.
