Credential Security Guide
The Risk
Credential stuffing is responsible for over 60% of unauthorized login attempts. When one site is breached, attackers use automated tools to try those same credentials on every other major platform.
The Solution
Use unique, complex passwords for every service. A password manager is the only effective way to manage the 100+ unique credentials the average user now possesses.
Our Privacy
We never see your password. Our "Zero-Knowledge" check uses mathematical hashes to verify breach status without ever transmitting your actual password or email to our database.
