Real-Time Leaked Email Detection Via API or Bulk Processing
Integrate leaked email checks against database breaches online through a real-time API, or by uploading a bulk list directly through the IPQS user dashboard. Leaked email address verification can greatly limit abusive behavior through credential stuffing detection and abuse from account opening fraud using stolen credentials.
Verifying leaked email addresses directly from your website, software, or app with the IPQS leaked email lookup API which includes example code to make integration an easy process. The leaked email checker can be performed live during account registration, user login, and other sensitive actions.
Detect leaked email addresses with one simple API lookup. Improve user data and account creation quality with accurate email address lookups that check thousands of databases across billions of exposed records online.
How Does Leaked Email Detection Work?
Search any email address against our leaked database consisting of over 5 billion leaked email addresses 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.
Further analysis can be performed using an email verifier tool which can also identify if the email is valid, risky, or leaked online. Our leaked email lookup tool works best with additional verification such as our compromised password checks and leaked username detection, for complete user protection.
What Leaked Email Address Lookup Data Is Available?
Deploy the leaked email address verification API or utilize our bulk list processing tools to detect if the email address 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 email was leaked online as well as the date of the breach. This makes it easy to identify a leaked email address that likely represent a fraudulent user with a compromised email address.
