What a breach exposure means

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.

Where does this data come from?

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.

What should I do if I've been breached?

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.
