The Chrome browser’s “not secure” warning is meant to help you understand when the connection to the site you're on isn’t secure. It is also a bit of a shaming motivation to the site's owner to improve the security of their site. But that process of getting the httpS site is not really easy in some cases and for non-tech average web users. 

Google made a warning announcement nearly two years ago and there has been an increase in sites that are secured. They started by only marking pages without encryption that collect passwords and credit card info. Then they began showing the “not secure” warning in two additional situations: when people enter data on an HTTP page, and on all HTTP pages visited in Incognito mode.

Their goal is to make it so that the only markings you see in Chrome are when a site is not secure, and the default unmarked state is secure. They will start removing the “Secure” wording in September 2018, and in October 2018, they will start showing a red “not secure” warning when users enter data on HTTP pages.
