Check your exposure

Check your own email or password against breach intelligence. Emails are confirmed with a one-time code first. Nothing is stored.

Your address is used for this one check and the code that confirms it. It is never stored, never sold, never added to a mailing list.

How this works

Prove it's yours

We email a 6-digit code. Without it, no lookup happens.

We check, we don't keep

Your address is sent to the breach sources and nowhere else.

You get a plan

A score you can recompute yourself, and reviewed steps to lower it.

What this never does

Store your email address, your password or your results
Send your password anywhere, in any form
Email you anything except the one-time code
Show you a step that a human hasn't reviewed

A research demonstrator for checking your own exposure. Not a commercial security product, and not a substitute for professional advice.
