LeakCheck – Check and Monitor Passwords & Accounts for Data Breaches! 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 – quickly, intuitively, and directly on your PC, without any sensitive data leaving your system.

A special highlight: the integrated password check. LeakCheck securely matches your passwords against the Have I Been Pwned database and instantly shows whether your credentials have been compromised. This allows you to identify risks early and take action in time. With the Professional Edition, you also benefit from automatic monitoring of your passwords and email addresses – whenever a new data breach is detected, LeakCheck opens automatically and notifies you immediately.

Securely check passwords – thanks to k-anonymity
A special feature: the secure k-anonymity check method. Your passwords are never transmitted in plain text – instead, only an anonymized hash fragment is sent to the Have I Been Pwned API. This ensures reliable results without compromising your security. Whether simple or complex passwords – LeakCheck checks all entries quickly and reliably against millions of known data breaches.

Check email addresses for data breaches – simple and clear
With LeakCheck, simply add your email addresses to the monitoring list and check them against the Have I Been Pwned database with a single click. For each affected address, you instantly see which data breaches it has appeared in – including the name, title, and date of each breach. This keeps you fully informed about all risks and allows you to respond quickly and effectively.

Dashboard – all security information at a glance
The clear dashboard of LeakCheck gives you an instant overview of the security status of your passwords and accounts. Safe and compromised entries are displayed separately – including the total number of detected data breaches. This allows you to immediately see where action is needed and set priorities accordingly.

Local data storage – securely encrypted on your PC
All data stored in LeakCheck – passwords and email addresses – is saved exclusively on your local PC. To protect against unauthorized access, LeakCheck uses the Windows Data Protection API (DPAPI), which encrypts your data with a key tied to your Windows user account. This keeps your sensitive data protected even if someone else gains access to your PC.

Free for private use – Professional Edition without limitations
LeakCheck is completely free for private use. The Professional Edition extends LeakCheck with automatic background monitoring – LeakCheck automatically checks your passwords and email addresses at regular intervals and notifies you immediately as soon as a new data breach is detected.
