In an announcement made by Google, there will be a change to how Chrome labels HTTPS and HTTP sites in the future. Beginning in September of this year, Google is going to remove the “Secure” wording and HTTPS scheme in Chrome version 69. In July 2018, Chrome will mark all HTTP sites as “not secure” in version 68.
This is how Chrome treatment for HTTPS pages will change:
When Chrome version 70 comes out in 2018, Google will begin showing the red “not secure” warning when users enter data on HTTP pages. Google said, “Previously, HTTP usage was too high to mark all HTTP pages with a strong red warning.” Now that things have swung in the direction of HTTPS, it now feels comfortable going forward with this change.
