Why should I compare two email addresses for breaches?

Comparing your emails helps identify shared breach exposures between your personal and work accounts or multiple accounts you own. Shared breaches indicate potential password reuse risks that require immediate attention.

Is the breach comparison tool free?

Yes, XposedOrNot's breach comparison tool is completely free to use. You can compare any two email addresses without creating an account.

How does the breach comparison tool work?

The tool searches our database of known data breaches for both email addresses you enter. It then shows which breaches affect each email, highlights shared breaches that appear in both, calculates risk scores, and provides actionable security recommendations based on the exposed data types.

What are shared breaches and why are they dangerous?

Shared breaches are data breaches that contain both email addresses you're comparing. They're dangerous because if you used the same password on both accounts, attackers who obtained credentials from that breach could access multiple accounts. This is called credential stuffing and is one of the most common attack methods.

Is my email stored when I use the comparison tool?

No, XposedOrNot does not store your email addresses or search history. Each comparison is performed in real-time against our breach database, and no personal data is logged or retained. Your privacy is protected.
