You may have noticed that when you visit certain sites, Google Chrome displays a little green padlock and the words "Secure" next to the address. That icon means that the site uses the encrypted web protocol HTTPS instead of plain old unencrypted HTTP.

You might also occasionally notice the words "Not Secure" next to an address in Chrome — typically when you're asked to enter a password or credit card number on a site that doesn't use HTTPS to protect your information. Starting with the newest version of Chrome released this month, Google will display the "Not Secure" warning more often.

For now, you'll see the "Not Secure" notice only on websites that ask you to submit information in forms or fields, including passwords, credit card information, as well as search terms. In the future, Google plans to display the warning for all unencrypted HTTP pages.

Because of the technical challenges in implementing HTTPS, many companies encrypt passwords and credit cards, but do not yet have HTTPS across their entire websites. While Chrome's security warnings may appear more frequently in the coming months, they don't necessarily mean your password or credit card information is being passed along insecurely. If you're concerned about a website that's marked as "Not Secure," contact the website owner directly and ask them about their website encryption practices.
