Google has been pushing website owners to make their websites more secure and convert to “HTTPS” since 2014. Recently, Google has sent out an email reminding website owners of just that. Currently, Chrome only shows a gray indicator on text fields of unsecured web pages. Google feels this doesn’t adequately show the lack of security an unsecured site offers. Google has already implemented this warning in credit card and password fields for unsecured websites in January 2017.
It is unclear if other browsers, such as Mozilla Firefox or Safari, will implement the same changes, but because Chrome is so large and has billions of users, it is important to take this update seriously. Chrome currently owns 64% of the market share and about 40% of all browsers are on the latest version of Chrome (W3 Counter).
