Leaked password verification can greatly limit abusive behavior through credential stuffing detection and abuse from account opening fraud using stolen credentials.
Check leaked passwords directly from your website, software, or app with the IPQS leaked password lookup API which includes example code to make integration an easy process. The leaked password checker can be performed live during account registration, user login, and other sensitive actions.
Detect leaked passwords with one simple API lookup. Improve user data and account creation quality with accurate leaked password lookups that check thousands of databases across billions of exposed records online.
How Does Leaked Password Detection Work?
Search any password against our leaked database consisting of over 5 billion leaked passwords from over 3700+ data breaches online. IPQS uses automated scanners that parse leaked data and compromised credentials from private forums, chat groups, dark web, and similar sources.
Our leaked password lookup tool works best with additional verification such as our compromised email checker and leaked username detection, for complete user protection.
What Leaked Password Lookup Data Is Available?
Deploy the leaked password verification API or utilize our bulk list processing tools to detect if the password has been exposed in a public or privately listed data breach online. Our tools will also append the name of the companies or database breaches where the password was leaked online as well as the date of the breach. This makes it easy to identify a leaked password that likely represent a fraudulent user with a compromised password.
