Google has announced a number of changes to their popular Chrome browser. From version 62 onward additional warnings will be displayed on http sites. These additional warnings will be displayed for example in Incognito Mode and when filling out online forms.
Google tells us that the changes will take effect in October. The search giant writes that in principle all data entered by users on a website should be inaccessible to third parties.
Therefore, from version 62, Chrome warns that the user is on an unsafe website if the user is filling out an online form on an unencrypted http page. It does not matter what type of form it is.
The second change is that incognito tabs show “not secure” if a Chrome user is on a http page. Google motivates this choice by suggesting that users who activate incognito mode expect their privacy to be better protected. However, on an http page, network traffic is visible for people on the same network, reasons the company.
Google has been making changes to the way the Chrome browser deals with http pages for a while now. In September last year, the company announced that from version 56 of the Chrome browser warnings will be displayed on websites that forward passwords and payment information, unless these websites communicate over https. Google now says that since this change there is 23 percent less traffic to http sites with password or payment information fields. In January, Firefox also began to warn for http pages with insecure login forms.
