📝 WalkthroughWalkthroughThe documentation adds RFC 8693 token exchange guidance, including client configuration, exchange requests and responses, delegation policies, and related Compass and SeaWatch references. The authentication documentation also adds the device authorization endpoint to discovery. ChangesToken exchange documentation
Priority: ⬇️ Low Estimated code review effort: 2 (Simple) | ~12 minutes Change: Other Suggested reviewers: Merge Risk: 🟡 Moderate · up to Readers could forward a token that the next service rejects or assume logout immediately invalidates a locally validated token. Clarify both points before merging. Security Architecture ReviewSecurity architecture risk: 🔵 Low · up to The new guidance broadly links exchanged-token validity to the user's session, but only explains revocation enforcement through introspection. Offline JWT consumers could misunderstand that guarantee. Documented client authorization, audience and scope restrictions, and bounded token lifetimes limit the potential exposure; this PR does not change runtime implementation. Retained concerns

exchanged token retaining the subject’s sid: limit the revocation guarantee to
introspection. Clarify that resource servers performing only local JWT signature
validation may continue accepting the token until exp unless they separately
check session status.

appropriate only when the next service is included in the token’s aud;
otherwise, exchange the token for that service’s audience. Include a different

| Mapped claims are not copied from the subject token. FerrisKey runs the protocol mappers again, those of the `audience` client when one is set, otherwise those of the requesting client, and only for the scopes the new token carries. Ask for `scope=profile` and the `email` claim is gone, even if the subject token had it. | ||

| Because the new token keeps the subject's `sid`, it lives and dies with the user's session. Log the user out or revoke the session, and the exchanged token stops working at introspection too. |

Reachability: External
Exploitability: Moderate
CWE: CWE-613 — Insufficient Session Expiration
Limit the session-revocation guarantee to introspection. The documentation also supports JWT signature validation against JWKS without a round trip. A resource server that validates only the signature does not learn that the session was revoked and can accept the token until exp, unless it separately checks session status.
Clarify the revocation behavior
-Because the new token keeps the subject's `sid`, it lives and dies with the user's session. Log the user out or revoke the session, and the exchanged token stops working at introspection too.
+Session revocation makes introspection reject the exchanged token. Resource servers that validate only the JWT signature locally do not learn that the session was revoked, so they can accept the token until `exp` unless they separately check session status.📝 Committable suggestion
‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

| ## When not to use it | ||
|
|
||
| - **A service calling another under its own identity**: use [client credentials](/en/discover/core-concepts/authentication#client-credentials). No user is involved. | ||
| - **One backend passing the user's token to the next hop unchanged**: forward the token and validate it at each hop. Exchange when the next hop should get less, or should know who acts. |

Limit forwarding to services named in aud.
Forward the token unchanged only when the next service is already included in the token’s aud. Otherwise, exchange the token for the next service’s audience. A resource server that performs audience validation can reject a forwarded token that does not name that service.
Update the forwarding guidance to include a different target audience as a reason to exchange the token.

Release notes
Adds the
v0.9.0entry torelease-notes.ts, in English and French, built from the commits betweenv0.8.0andmain. It covers token exchange, back-channel logout and consent, the password hash import that lets the CLI bring Supabase users over with their passwords, webhooks, i18n and the realm isolation work.publishedAtis a placeholder (2026-10-03) and the GitHub links point to av0.9.0tag that does not exist yet. Set the date and merge this PR when 0.9.0 is released, since the release notes page uses the first entry as the latest release.
