TOOL 02
Find out if your email address has appeared in known data breaches, and what was exposed.
Enter an email to scan breach databases.
When a service you use is breached, your email — and often passwords, names and more — can end up in lists traded by attackers. Reusing those passwords anywhere puts those accounts at risk.
Your email is used only to run the lookup. It is hashed before storage and never sold or shared.
We check your address against a large database of known, publicly disclosed breaches. A match means your email appeared in that breach — not that any single account is currently compromised.
Change any reused passwords immediately, turn on multi-factor authentication, and consider a password manager. If passwords were exposed, prioritise every account that shares that password.
