Check if your email address has been exposed in any known data breach. Find out if your passwords are compromised and protect your accounts before cybercriminals use credential stuffing to break in.
Scanning known data breach databases...
If your email appears in data breaches, the associated passwords are compromised. Generate new, unique, and uncrackable passwords instantly.
🛡️ Generate Secure PasswordsThis free email breach checker queries the public API of Have I Been Pwned (HIBP), created by Troy Hunt, a recognized cybersecurity expert and Microsoft Regional Director. HIBP is the world's most comprehensive data breach database, with over 13 billion compromised records from more than 700 known breaches including LinkedIn, Adobe, Dropbox, MySpace, and hundreds more.
Yes, completely. We only send your email to the HIBP API for the query. We do not store, log, or save your email anywhere — period. The query is made directly from your browser to HIBP's servers over an encrypted HTTPS connection. No registration or account creation is required.
A data breach occurs when a hacker gains unauthorized access to a company's servers and steals the user database. This can include emails, passwords (sometimes stored in plain text), usernames, phone numbers, physical addresses, and even financial information like credit card numbers. That stolen data is then sold on the dark web, where other cybercriminals use it to break into your accounts across multiple services.
If your email appears in a breach and you were using the same password across multiple services, an attacker can access all of those accounts. This attack method is called credential stuffing — and it's responsible for over 80% of personal account hacks. That's why it's critical to use a unique, random password for every service and store them all in a password manager.
Yes. The check uses the public Have I Been Pwned (HIBP) API. GenerarPassword does not store your email on our servers; the request is made from your browser to HIBP over HTTPS.
It is an incident where user data is exposed (emails, passwords, etc.) through attack or error. That data can be reused in attacks such as credential stuffing.
A public service by Troy Hunt that aggregates known breach data so you can see if your email appeared. We use its API to show results.
We do not save your address in our database. The query goes to the HIBP API; see HIBP privacy policy for processing on their side.
Change unique passwords per service, enable 2FA, and stop reusing the same password. Use our generator and password strength checker.
Yes, one check at a time. Repeat for each address you use for logins.
HIBP depends on publicly known and reported breaches. Not appearing does not guarantee a never-disclosed incident.
Yes for any valid email. Check each alias or account you use because breaches may list one address or another.
