Has your email been in a breach?

We check your address server-side against the largest public breach database. We never save your email and never sell or share it.

One email is a snapshot. A household is an ongoing target.

HackFirstAid Household watches every address in your house continuously, alerts you the moment something new appears, and walks each person through what to do.

We never disclose breach passwords or other sensitive specifics that could be used to harm you. This tool is informational — your account security depends on action you take after.
