## Notes
Notes by Topic

### General
- Takashi presents current state of efforts
- Next OAuth SIG meeting will be held on Wednesday 1 October 2025.
3 September 2025:
- Takashi: I cannot attend the next meeting because I will attend MCP Developers Summit in UK.
- Takashi: Keycloak AI SIG started. What both OAuth SIG and AI SIG do might be overlapped (e.g., MCP support). I joined AI SIG, so I will consider arranging that.
- Takashi: I renamed the name of #1 item from "Workload Identity - Transaction Token, SPIFEE" to "Workload/Agentic Identity" because this item can also incorporate Agent Identity in AI industry.

## New Support

### 1. Workload/Agentic Identity
3 September 2025:
- We include the specification [OAuth Identity and Authorization Chaining Across Domains](https://datatracker.ietf.org/doc/draft-ietf-oauth-identity-chaining/).
- Several (3?) parties work on the same topic (SPIFEE client authentication).
- Dmitry: consentrates on Transaction Identity and OAuth Identity and Authorization Chaining Across Domains.
- We will have breakout session for this working item (4PM london time).


### 2. OAuth 2.0 for First-Party Applications (FiPA)
3 September 2025:
- Adorsys considers 2nd phase PoC by incorporating comments on the discussion.

### 3. Shared Signals Framework (SSF)
3 September 2025: 
- Shared Signals Final Specifications Approved
- Specs: OpenID Shared Signals Framework, OpenID CAEP, OpenID RISC
- see: https://openid.net/three-shared-signals-final-specifications-approved/
- see: https://sgnl.ai/2025/09/sgnl-welcomes-the-publication-of-the-final-shared-signals-and-caep-specifications/
- Added SSF Transmitter support to my PoC
- Currently implementing OIDF Conformance tests for SSF Receivers

### 4. OpenID Federation 1.0 (OIDFED)
3 September 2025:
- Adopt of OpenID Federation : European Open Science Cloud and eduGAIN global network of academic Identity & Service providers (not that of GRNET mentioned)
- Alexander Schwartz mentioned about knowing the general showcase of OpenID Federation for proceeding with PR during 'Keycloak Maintainers & Friends'. Any help with other cases needed it, escecially automatic registration as OP?
### 5. Attestation-Based Client Auth
3 September 2025:

### 6. Model Context Protocol (MCP)
3 September 2025:
- Takashi: no progress. Until the PRs are merged, I presented in KeyConf 25 Amsterdam the workaround for keycloak to comply with MCP specification's authorization part (2025-06-18 ver).

## Refinement

### 7. OpenID Verifiable Credentials Issuance (OID4VCI)
3 September 2025:
- Focusing on Draft 15 and 16 epic issue.
- It seems that Final spec voting in Sep is for Draft 17.

3 September 2025:
- Takashi: It seems that there is no progress.

### 9. Demonstrating Proof-of-Possession (DPoP)

- Takashi: It seems that Keycloak 26.4 (the end of this Sep release expected) support Passkeys as officially supported feature.

- Takashi: no progress.
