Google announced plans to increase the usage of the “Not secure”” indicator on sites loaded via HTTP. Chrome will mark any HTTP page as “”Not Secure”” starting with Chrome 62. Google also admitted that it does plan to show the flag in the URL bar for all HTTP pages somewhere in the future. The Chrome team justified this improvement by saying that “”when users browse Chrome with Incognito mode they likely have increased expectations of privacy”” Google released the following GIF to showcase how the feature will work.”
