Windows 11* and MacOS also do the job as long as you're using hardware bound passkeys.

* I don't want to speak past my own experience so checking my work, Windows can store passkeys in a TPM if available but falls back to storing on disk... https://helgeklein.com/blog/checking-windows-hello-for-busin...

I was looking for an answer to this when it comes to using Edge password manager in particular, it uses Windows Hello as far as I know and while it does make 'synced' passkeys they don't seem to be usable anywhere than the original machine. Useful when reinstalling Windows at least.

https://yourpasskeyisweak.com does not mention Edge.
