With so many different passwords to keep track of, do you ever wonder if they're secure enough? Now there's a website to let you know if your password has been hacked, according to Lifehacker.

Shouldichangemypassword.com lets you type in your email to find out if your password has been hacked. The site uses a number of databases that have been released by hackers to the public. I haven't used the site yet, but I plan on checking my email addresses later to find out.
