callerOrigin

[annevk]

What do you mean by origin of the caller?

[equalsJeffH]

you're apparently referring to..

Set callerOrigin to the origin of the caller.

..in both..
https://w3c.github.io/webauthn/#makeCredential
https://w3c.github.io/webauthn/#getAssertion

"origin of the caller" refers to the origin of the document whose javascript is invoking either makeCredential() or getAssertion().

perhaps you could suggest more appropriate terminology?

[annevk]

So these APIs are not available in workers?

Note that "document whose JavaScript" is woefully imprecise since the JavaScript can come from anywhere.

What you likely mean is something like "current settings object's origin" (see WHATWG HTML Standard).

it is not entirely clear at this time (seems to me) -- see also: #199
