> If you wanted to add a device to the HN account you'd login, go to the settings, and generate another pub/private key for the new device rather than the traditional "change password".

I still don't understand how do I do that.

Let's say I registered account using iPhone. Now I want to log in with my Linux workstation. So I pick up iPhone, go to the https://news.ycombinator.com/settings click "Add device" and then what?

I guess something like "recover password" workflow? Like I type my e-mail on new device, receive login link and then via login link I can register new device?

This depends on the implementation.

If you are in Apple world, your keys are synced between iOS and macOS (and saved in Secure Enclave, so you need TouchID/FaceID to complete flow.) In 'Google' world, you can use them between Android devices and Chrome browser.

However, if you access from unsupported app/device (e.g. use Apple Passkeys and want to access from browser on Linux machine), you can always just scan QR code with phone, and use it to log-in.
