The ongoing changes to Chrome's security features.

TL;DR
Google is retiring the lock icon in Chrome and replacing it with a new "tune" icon as part of a Material You-themed redesign of the browser. The lock icon will be replaced in September 2023, as Google claims that only 11% of users understood its intended purpose. The new tune icon will encourage users to click through and access more information about their security and connection settings. The page controls under the tune icon will remain unchanged, and plaintext HTTP will still be marked as insecure. The lock icon will also be removed entirely from Chrome on iOS.
