Have I Been Pwned

Have I Been Pwned is a free website, created in 2013 by Australian security researcher Troy Hunt, that tells you whether your email address appears in known data breaches. You visit haveibeenpwned.com, type your email address, and it lists each breach that included it, along with what kind of data leaked, such as passwords, phone numbers or addresses. You can also sign up for free notifications to hear about future breaches. It never asks for your password. A separate feature, Pwned Passwords, lets password managers and websites check whether a password has appeared in leaks, using a method that does not reveal the full password. The word "pwned" is gamer slang for "owned", meaning defeated or taken over.
