About the Email Breach Check
This tool checks whether an email address has appeared in known data breaches. When companies get hacked, stolen credentials and personal data end up in leaked databases traded by criminals. Knowing your address is exposed lets you act before those leaks are used against you.
If your email shows up in a breach, it means passwords or other data tied to that address may be circulating. The essential response is to change any reused passwords and turn on two-factor authentication on the affected accounts.
Enter an email address to check it privately against known breach data. Use it to audit your own addresses and stay ahead of credential-stuffing attacks.
