Have I Been Pwned (HIBP) has undergone a significant update, incorporating passkey support, k-anonymity searches, and substantial speed enhancements. The platform now handles hundreds of thousands of daily website visitors, tens of millions of API queries, and hundreds of millions of password searches. HIBP processes billions of compromised records annually, sourced from breached companies, white hat researchers, hackers, and law enforcement agencies. A new bulk domain verification API has also been introduced, catering to the diverse user base, including infosec professionals and general users. The update aims to improve the overall efficiency and security of the service, which has become a crucial tool for individuals and organizations to check for compromised passwords and credentials1. This matters to security practitioners as it provides a more efficient and secure means of verifying password breaches, allowing them to take proactive measures to protect their online presence.
