Google plans to replace the padlock icon indicating website security in Chrome with a “tune” icon in September 2023 as part of a browser redesign. Google’s research found that only 11% of participants understood the intended purpose of the lock icon.
The new icon better represents control menus and encourages users to click through to access more information about their security and connection settings. Over 95% of Chrome webpages loaded on Windows now use HTTPS, making it the default connection. The new icon will continue to mark plaintext HTTP as insecure on all platforms.
