Google is changing the lock icon in Chrome because it believes 'security should be the default state'
Visit a secure website (that is, one that loads over HTTPS) in Chrome, and you'll see a lock icon in the address bar. But this is set to change. Google has announced plans to remove the familiar padlock icon, providing a number of reasons for a decision that many users will regard as a step in the wrong direction.
Among the arguments in favor of removing the icon is that HTTPS is the norm rather than the exception, and that the simple fact a site uses a secure connection is in no way indicative of its inherent trustworthiness.
