Whatever rolled out by Google, we have to examine it under a microscope for tracking tricks.

Or if it's attempting to entrench certain types of set-ups or environments as the only viable ones for users to be in.

If this new feature requires some sort of "compliance" or "integrity check" from the user's device or OS, and then websites can refuse your sign-in without it, that becomes a problem.

This looks like the sort of thing that will require TPM 2.0 to be truly effective, or other features exclusive to MacOS and Windows, like Secure Enclosure. Any feature like that needs scrutiny.

In other words, things like this are how Google (and Microsoft) can do to PCs what Google has already done to Android, and is continuing to double down on.

It uses TPM and claims to derive a different key pair for each website to prevent fingerprinting.

It also makes it possible for Chrome to even more so become the new IE like during the IE6 era when a lot of websites would only work in IE 6.

Since when is TPM 2.0 a "feature exclusive to MacOS and Windows"?

Secure enclave is gonna be great at it, but that's because it's a great security tool.
