<kpaulh> +present

<scribe> scribe: weiler

nadalin: We're meeting at TPAC; plan accordingly. Day not certain.

selfissued: jeffh, please report on what you've been up to.

jeffh: finished 427 and merged it.

jyasskin: fine.

jeffh: 427 could still use review. submitted PR 489. cleans up many easy issues.

nadalin: skip over 375 (editorial).
... 379:

angelo: I think I've addressed everything.

jeffh: this needs some review

angelo: @@ is not part of credential mgnt; don't see why this should be added.

https://github.com/w3c/webauthn/pull/379

"Add isPlatformAuthenticatorReady function to the API surface "

angelo: add mike west as a reviewer?

jyasskin: would be nice to have example of the use of this func (but I've not read this spec)

https://github.com/w3c/webauthn/pull/460

Adds requireUserVerification option in AuthenticatorSelectionCriteria

@1: no changes not worth discussion today:

https://github.com/w3c/webauthn/pull/476

rolf: this PR is about adding one option.

selfissued: is this just a boolean or richer?

dirk: sees like a nice-to-have, but since we don't have interop impl. w/o this, let's get a smaller version out the door and save this for future work.

nadalin: we're in the process of rewriting the charter and I've been thinking about work for the next version. this might count.

sellfissued et al: concur

giri: auth selection criterion?

nadalin: suggested to postponed 476.
... now 477

https://github.com/w3c/webauthn/pull/477

jyasskin: I support dirk's request to postpone, @2

nadalin: any objection to postponing 476/477?
... [silence]

https://github.com/w3c/webauthn/pull/479

rolf: more generic... @3 ... by model identifier.

selfissued: ietf has a doc saying that it's useful to say what was used but not to limit what may be used.
... trying to encode knowledge re: what ID provider does in an RP is just asking for breakage.

jeffh: mike jones refers to: https://tools.ietf.org/html/draft-ietf-oauth-amr-values
... some RPs will only support a certain class of authenticators in the forseeable future.
... corporate perspective is tht only certain authenticaotrs will be supported.

nadalin: but this can be picked up as reg time

jeffh: but there's a UX issue

dirk: current dictionary is okay. propose leaving this as an extension.

giri: opposed.

dirk: in dict now: is auth built into platform or cross-platform. 2) supports user verification or not

jeffh: require resident key and attachment are current ones in the spec.

selfissued: alexei's PR for user verification needs to go in, also.

jeffh: AAGUID list is optional. pretty simplistic. does not cause harm. aguid is a good hook for us to have.

angelo: we should learn more about how it's been used.
... how do you select authenticators based on aaguid?

jeffh: not sure how our mobile app does it.

christiaan: [describes model of shopping for a laptop and finding that some have an aaguid not on some list...]

angelo: concerned that RPs have to maintain large list of approved authenticators.

wseltzer: wondering if this is worth a specific write up and Q on the mailing list, to make sure people are focused on the argument around it. clearly some differences in understanding.

nadalin: will anyone step up to write this up? if not, I'm inclined to leave it for v2?

dirk: and as an extension in this version?

nadalin: defer this PR; leave text as extension?

dirk: support

angelo: okay.

[giri opposed, but has dropped from call.]

rolf: doesn't change my mind, though I can accept that I'm in the minority.

jeffh: +1

nadalin: put this to list.
... meet again next week
