<wseltzer> nadalin: tentatively, cancel 7 and 21 Oct.

<wseltzer> ... if needed, we can reschedule

tony: get wd-04 done before end of month
... end of Oct. for CR
... completion

akshay: I am implementing ctap 2.1 for the platform
... should be end of month

tony: I don't know status of safari
... we need two interoperable implementations

JTan: we won't be ready

tony: left with edge and Chrome

bradley: do we do it with ctap 2.0 only

agl: we don't talk about 2.1, think just demonstrate what is in this spec.

endy: I can't predict the director response on the code base, and if it is two implelmentations

akshay: they can be behaving differently

tony: when w do the implementation w can write this into the interop report

bradley: firefox could be the other implemenation if we don't add 2.1 stuff.

tony: open PRs


agl: I need to catch up


agl: nina is not here

tony: seems ready to go

akshay: looks good to me. merge

tony: yes, merge


jTan: still waiting for reply from lawyers.

tony: what do we do here

jeffH: wait.
... this is not essential, I think.

tony: leave open


elundberg: good to go

akshay: what is solution here? are you saying RP should send fake credentials.

elundberg: this is an attack that effects users that don't use web authn
... there are other alternatives.

bradley: some discussion on this in the press. they said we were encouraging discovery of accounts to brute force

elunberg: why is the allow list empty?

bradley: the point is the attacker can look into different second factors

ellundberg, maybe say non-empty and failure

scribe: I will fix that

tony: are you OK making changes and merging
... any objections?



tony: this is feature policy

jeffH: this has been split into #1479, do feature policies in another action

jc_moz: would rather see this are re-base

jeffH: this looks fine to me, let's figure out how to land this.

JC_moz: I think we can land this once it's in shape.

tony: includes 1479?

jc_moz: yes

tony: let's do this is two steps


jc_moz: follow-up to move extension before PR
... remove extension
... need to see if we can publish a note out of this group, if not, we can move to WICG

tony: this is OK?

<wseltzer> https://wicg.io

wendy: we can publish a non-normative note. WICGis community group that works from github.

jc_moz: part of point, this is crypto function we should get wider review
... WICG is a good place to do this.

tony: everyone OK on moving forward?

bradley: prefer keeping the note inside the working group, and get wider input

selfissue: I agree. we control our own destiny

<wseltzer> nadalin: any objections to publishing as a note? hearing none.

tony: we have a few untriaged issues


jeffH: dinosaur

tony: goal is to get this done by CR?

jeffH: this is background


tony: this is to remove this. this can land in wd-04


nsteele: this is in the community group

bradley: decided to keep this around to track the issue. no spec changes


jtan: no update on this, apple attestation


tony: john and mike, can you look at this

bradley: will be adding wording

tony: what about interoperable implementations

jc_moz: won't have ctap2

bradley: don't need to do ctap2

jc_moz: i'll have to get back to you on that.

tony: any more issues?
... adjourn
