About this tool
This tool uses Have I Been Pwned (HIBP) - the world's largest database of data breaches. Check if your password or email has appeared in known data breaches.
Your password is hashed locally. Only the first 5 characters of the hash are sent to the API (k-Anonymity).
What to do if your data was found in a breach?
Change your password immediately
If you use the same password on other services, change it everywhere.
Enable 2FA
Two-factor authentication significantly increases account security.
Use a password manager
Unique, strong passwords for each service are the foundation of security.
