Google Chrome will no longer show whether a site you are visiting is secure and only show an indicator when you visit an insecure site. Google is testing a new feature that removes the lock icon for secure sites. This feature is available to test in Chrome 93 Beta, and Chrome 94 Canary builds by enabling the ‘Omnibox Updated connection security indicators’ flag. Google has added an enterprise policy for Chrome 93 named ‘LockIconInAddressBarEnabled’ that can be used to enable lock icon again on the address bar.
