Is your password for sale? Find out in a second.
A free check for citizens and companies: has your e-mail, phone or domain appeared in known breaches. The query is hashed in the browser, so nothing reaches us in plain text.
- Email / phone
- Password / domain
- Zero-knowledge
- Free
Why it matters
The problem
An infostealer harvests passwords even from a phone’s browser and posts them to a forum within hours. Most people learn this after the attack, when the attacker is already inside.
Our answer
Data Breach Check shortens that distance: the check is free, anonymous and takes a second. For companies, domain monitoring sends a notice when a new breach appears.

Questions
All productsIs it really free?
Yes. For citizens the check is free and needs no registration. Domain monitoring for companies is free too; only ownership is verified.
Is it safe to enter my password?
The password never leaves the browser: a hash is computed and only its prefix is sent. The server holds neither the full hash nor the password.
What should I do if something is found?
Change that password everywhere, enable MFA, revoke active sessions. The steps are shown on the result page.
Where do the breaches come from?
Open sources, closed forums and infostealer logs. Data is neither bought nor redistributed.
