What to expect from an ideal product

  1. LeakCheck runs entirely on your Windows PC, meaning your passwords and email addresses never travel to an external server or third-party cloud during the check.
  2. The software compares your credentials against millions of real data breach records, so you get results tied to actual leaked datasets, not theoretical risk scores.
  3. If you have ever reused a password across multiple sites, LeakCheck tells you exactly which accounts are exposed before an attacker connects the dots.
  4. Setup takes minutes and requires no technical background, making it practical for everyday users who want answers without reading documentation.
  5. Checking your email address in LeakCheck shows which specific breaches it appeared in, so you know whether to change one password or ten.
