GitHub Supports Web Authentication (WebAuthn) for Security Keys
In a somewhat related vein: it would be really fantastic if Github allowed the same SSH key (in my case: a Yubikey-resident SSH key) on multiple accounts; we use separate accounts for different clients, and Github's refusal to allow an SSH key to be used on multiple accounts means I can't use Yubikey SSH keys for those.<p>I get that this is a niche-y concern. :)
