From the beginning, security has been one of Chromes core principles and one of the biggest changes in Chrome 68 is displaying Not Secure warnings for websites not encrypted with HTTPS.
Nearly two years ago, Google announced that Chrome would eventually start marking all sites that are not encrypted with HTTPS as â€œNot Secure'' as an attempt to motivate site owners to improve the security of their websites. With the release of Chrome 68, this has now become a reality.
Starting in October 2018, Google plans to start showing a red "Not Secure" warning when users enter data on pages that are not served using HTTPS.
