LeakCheck compares your passwords and email addresses to millions of known data leaks β right on your PC. Discover LeakCheck, the user-friendly Windows software for protecting your digital identity. With LeakCheck, you can securely check your passwords and email addresses for known data breaches β quickly, intuitively, and directly on your PC, without any sensitive data leaving your system.
What to expect from an ideal product
- LeakCheck runs entirely on your Windows PC, meaning your email addresses and passwords are never uploaded to a server or shared with third parties during the scan.
- The setup takes under five minutes β download, install, and start scanning your first email address for data breach exposure without any technical configuration required.
- LeakCheck cross-references your credentials against millions of known leaked records, giving you a clear verdict on whether your password has been compromised in a real-world data breach.
- Unlike browser-based tools, LeakCheck lets you batch-check multiple email addresses in one session, making it practical for users managing more than one personal or professional account.
- If a leak is detected, LeakCheck shows you which breach your data appeared in, so you know exactly which password to change and where the exposure originated.
