Google is making another change to the way Chrome indicates HTTPS and HTTP sites. Starting with September’s release of Chrome 69, the world’s most popular browser will stop marking HTTPS sites with the green “secure” label in the address bar—it believes that users should expect this to be the default state. Then in October, Chrome will start showing a red “not secure” warning when users enter data on HTTP pages.
More than half the internet now uses the HTTPS protocol, which encrypts data in transit. The secure connection helps prevent against man-in-the-middle attacks and protects data from the prying eyes of third parties.
