Have I Been Pwned

Have I Been Pwned is a vital cybersecurity resource designed to help individuals and organizations assess their exposure to data breaches. By aggregating information from hundreds of high-profile security incidents, the platform allows users to search for their email addresses or phone numbers to see if their personal data has been leaked online. Beyond simple lookups, the site offers a "Pwned Passwords" feature that checks if a specific password has appeared in any known data dumps, helping users avoid compromised credentials. Created by security expert Troy Hunt, the service emphasizes user privacy and proactive digital hygiene through its free notification system. Users can subscribe to receive immediate alerts whenever their information appears in a new breach, enabling them to take swift action by changing passwords or enabling multi-factor authentication. This transparency empowers people to regain control over their digital identities and stay informed about the evolving landscape of online security threats.
