Google said that in 2018 the Google Chrome browser will mark all websites that do not use HTTPS encryption as "insecure".
This means any site that does not display a green padlock will be marked as insecure in the address bar of the pro.letterof browsing.
Emily Schechter, Google Chrome Security Manager, confirmed with a post on Google Chrome company blog that the changes will come into effect with the release of Chrome 68 in July.
"In recent years we have been striving for a more secure web, strongly supporting sites that adopt HTTPS encryption," the blog post said Thursday.
It seems that Google's effort is escalating, gradually pushing more and more people Webmasters to adopt it protocol HTTPS, a secure encryption standard.
Please note that using HTTPS means that data sent from your computer or device to a website is safely transported and can not be intercepted by an attacker.
Google has used several other tactics, including ranking sites using HTTPS better in the results search, as an incentive for webmasters to adopt it technology.
