Getting alot of sales calls, spam in your emails or hacked accounts?
The creator Troy Hunt had created HIBP as a free resource for anyone to quickly assess if they may have been put at risk due to an online account of theirs having been compromised or “pwned” in a data breach. He wanted to keep it dead simple to use and entirely free so that it could be of maximum benefit to the community.
This site came about after what was, at the time, the largest ever single breach of customer accounts — Adobe. Troy often did post-breach analysis of user credentials and kept finding the same accounts exposed over and over again, often with the same passwords which then put the victims at further risk of their other accounts being compromised.
