Overview
- Troy Hunt indexed the dataset into Have I Been Pwned after spot‑checking with affected users, confirming many passwords are real and in active use.
- About 625 million passwords were previously unseen by HIBP, pushing its database beyond roughly 17 billion exposed accounts.
- The collection aggregates credentials from years of prior breaches and credential‑stuffing lists rather than a new hack of a major provider.
- People can check exposure by searching emails on haveibeenpwned.com and by using the Pwned Passwords tool without revealing their actual passwords.
- Security guidance urges changing compromised and reused passwords, enabling two‑factor authentication, using password managers, and moving to passkeys where available.
