What this checks

This checks the email against a public breach corpus and returns the number of breaches, the most recent date, and the data classes exposed (emails, passwords, etc.).

Why it matters

Reused or breached credentials are a leading cause of account takeover. Knowing an address is exposed tells you to rotate passwords and enable phishing-resistant MFA.

How the detection works

A keyless breach-intelligence provider is queried for the address. Only public-safe fields are returned: breach name, date, and data classes. Specific passwords are never returned.

FAQ

Do you store the email I check?

No. The queried address is not written to our usage log; only the verdict (exposed/clean) is recorded.

What should I do if I am exposed?

Change the password anywhere it was reused and turn on multi-factor authentication, ideally an authenticator app or passkey.
