A Scottsdale man launched a website that will allow you to check to see if any of your online accounts have been compromised.
John Sabo started FreeHackReport.com to help people protect themselves.
"As a former hacker myself, I understand the challenges in data security," said Sabo.
Sabo says he knows the interworkings of the web.
"My goal is to have as many people view their data, understand it and protect themselves and therefore taking the power back out of the attacker," said Sabo.
Sabo has more than two billion profiles of people's information.
You can check if any of your passwords are known to someone other than yourself by visiting his website.
