A majority of Internet users rarely change their passwords and use the same one for years. While this is an easy way to manage and remember passwords, it is also an easy way for cyber criminals to obtain them. According to Intel, 90% of passwords are vulnerable, and it only takes five minutes for a hacker to crack them.

As a result, Intel, along with supporters like Microsoft, Toshiba, Samsung and others, have dubbed today, May 7, World Password Day. It is meant to be a public service to remind the millions of Internet users to protect their online identity and change their passwords.

“You should change your important passwords as often as you change the oil in your car,” said Intel. “Upgrading your password takes five minutes and can save you hours of trouble down the line.”

This year Intel has launched Passwordday.org, a website dedicated to password education.

On the website, users can test whether or not a website is still affected by the Heartbleed bug with McAfee’s Heartbleed Test tool. They can also check the strength of their password, and look at the do’s and don’ts of creating a password.

Also available on the site is an online “Password Blaster” game that allows users to destroy leaked passwords.

“If you see one of your passwords, it’s a good sign you need to change it,” according to the game.
