What it does
Our service helps protect credentials and find passwords which were forgotten long time ago. Among our clients are regular people, companies banks, IT experts and analytic centers.
Search 10 billion leaked records from 1,366+ data breaches. Check if your email, username or phone number has been exposed — instant, free and confidential.
Each report lists the exact fields found for your query — logins and passwords, names, contact and location details, and records pulled straight from info-stealer logs. The logins tied to a breached account — and the passwords stored with them. The person behind the account: their names and date of birth. How to reach the person and where they are — phone, address and postal code. Credentials captured directly by info-stealer malware, together with the exact websites they were entered on. LeakCheck is run by a company registered in England & Wales and processes personal data under UK GDPR and the Data Protection Act 2018. Anyone can make their records unsearchable through our data removal…from leakcheck.io
