>They don't even support Webaunth.

Apple iCloud supports WebAuthn as of two months ago: https://www.apple.com/newsroom/2022/12/apple-advances-user-s...

Google has supported WebAuthn for quite a while as well: https://landing.google.com/advancedprotection/

I'm not very familiar with Microsoft's ecosystem and I believe it's a bit more fragmented, but it seems that at least some portions of it do support it: https://support.microsoft.com/en-us/account-billing/how-to-g...

I tried WebAuthn for the first time on MacOS a few weeks ago (on the WebAuthn demo site), and the site inexplicably didn't support the key that I've been using for the last 4 years for 2FA. It didn't even bother explaining what the problem was, but I assume they want me to buy Yet Another Physical Device if I want to participate. It's definitely still not there, and at this point I don't have high hopes for the future.

Both Apple and Google use webauthn as second factor, never the first.
