RE: Accidental Tech Podcast 592, which speculates that macOS Sequoia pre-installs the iCloud Passwords browser extension for Chrome users.

It absolutely does not.

The discussed JSON file supports the user-installable extension communicating with the OS to securely access password data. See https://developer.chrome.com/docs/extensions/develop/concepts/native-messaging

The new Passwords app does encourage Chrome and Edge users to install the extension on first launch, however. Button opens the browser to the relevant Chrome/Edge Web Store page.

@rmondello does the browser extension support Linux use now? I have to use Ubuntu for work so having support would be great.
@Geekpulp @rmondello No, it doesn’t. It works only on macOS and Windows.
@szymonzielonka @rmondello makes me wonder why? Technical limitation? Not a priority? Both?
@Geekpulp @rmondello I suspect that the problem is the low popularity of Linux (not counting servers).
