I think you're right about the first part...a passkey being tied to a single account on a single site.

But not the second: on Github for example you can have multiple passkeys for the same account.

People mention the "only a single passkey instead of multiple passkeys" issue because they run into some websites such as PayPal that only let you add one passkey. E.g. :

But not the same ssh key on multiple accounts.
