<p class="MsoNormal"> PR #119: fixes #1425 - adds security consideration for confidentiality response (same-device)<o:p></o:p></p>
<p class="MsoNormal"> We agreed to merge this<o:p></o:p></p>
<p class="MsoNormal"> Christina Bauer is also doing more security analysis of #1425<o:p></o:p></p>
<p class="MsoNormal"> PR #110: implementation consideration for cross device flow<o:p></o:p></p>
<p class="MsoNormal"> We discussed the wording "typically from the Internet", which raises unanswered questions<o:p></o:p></p>
<p class="MsoNormal"> PR #101: Fetching presentation definitions from a remote repository<o:p></o:p></p>
<p class="MsoNormal"> We think this can be merged after resolving merge conflicts<o:p></o:p></p>
<p class="MsoNormal"> PR #120: Issuer Handling SIOP<o:p></o:p></p>
<p class="MsoNormal"> This new PR addresses issue #1400<o:p></o:p></p>
<p class="MsoNormal"> Torsten said that this simplified the specification<o:p></o:p></p>
<p class="MsoNormal"> We discussed Vittorio's comment on #1400<o:p></o:p></p>
<p class="MsoNormal"> We agreed to talk about this in the regular working group call on 10-Feb-22<o:p></o:p></p>
<p class="MsoNormal"> Because this is an architectural addition that could also be used by existing OPs<o:p></o:p></p>
<p class="MsoNormal"> George used the analogy of having both personal and business cards in his wallet<o:p></o:p></p>
<p class="MsoNormal"> He asked about the privacy implications of having the issuer identify the wallet<o:p></o:p></p>
<p class="MsoNormal"> Torsten points out that then there wouldn't be a way for an RP to know whether you're talking to a SIOP or not<o:p></o:p></p>
<p class="MsoNormal"> He asked for input on that topic<o:p></o:p></p>
<p class="MsoNormal"> We discussed filing a separate issue on this topic<o:p></o:p></p>
<p class="MsoNormal"> Torsen said that he'd like SIOPs to be both third party OPs and self-hosted OPs<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>

<p class="MsoNormal"> #1417: Defining SIOP and the scope of its specification<o:p></o:p></p>
<p class="MsoNormal"> Stephane requested that we clearly define what we mean by SIOP in one place<o:p></o:p></p>
<p class="MsoNormal"> SIOPs issue self-signed ID Tokens<o:p></o:p></p>
<p class="MsoNormal"> Whether it's self-hosted is a separate issue<o:p></o:p></p>
<p class="MsoNormal"> Mike said that we should discuss the implications of whether the OP is self-hosted or not<o:p></o:p></p>
<p class="MsoNormal"> This is related to both #1400 and #1399 (whether we support additional response types)<o:p></o:p></p>
<p class="MsoNormal"> Torsten suggested we address this after the discussions on #1400, etc. have played out<o:p></o:p></p>
<p class="MsoNormal"> #1426: Clarification of "sub" value<o:p></o:p></p>
<p class="MsoNormal"> We should state that the "sub" is always about the End-User<o:p></o:p></p>
<p class="MsoNormal"> #1427: Credential issuance with PKCE or without?<o:p></o:p></p>
<p class="MsoNormal"> Mike said that it's a longer discussion on the pros and cons of using PKCE<o:p></o:p></p>
<p class="MsoNormal"> Note that Connect Core flows don't use PKCE and requiring it would be a breaking change<o:p></o:p></p>
<p class="MsoNormal"> OAuth 2.1 explicitly does not require PKCE when OpenID Connect is used<o:p></o:p></p>
<p class="MsoNormal"> Torsten said that FAPI requires PKCE<o:p></o:p></p>
<p class="MsoNormal"> #1429: Replace JWK Thumbprint URI with JWK URI<o:p></o:p></p>
<p class="MsoNormal"> We ran out of time to discuss this issue<o:p></o:p></p>
<p class="MsoNormal"> People are requested to read it and respond with issue comments<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Next Call<o:p></o:p></p>
<p class="MsoNormal"> The next Connect call will be Monday, February 7, 2022 at 3pm Pacific Time<o:p></o:p></p>
