Summary

This PR removes the deprecatedKeyConnectorUrl property from the root of the identity token response. The property was deprecated over 2 years ago and clients should now be reading it fromUserDecryptionOptions.KeyConnectorOption.KeyConnectorUrl instead. The changes are minimal and focused: removing one line of code that set the root-level property and updating tests accordingly.

Findings

Finding 1: PR title and description should clarify client compatibility requirements

💭 The PR description mentions "ensure mobile won't be affected negatively" (author's own comment), but doesn't explicitly state which client versions are compatible with this breaking change. Consider adding:

• Minimum supported client versions that have migrated away from reading the root-levelKeyConnectorUrl
• Link or reference to when clients completed the migration (the linked clients PR is helpful but may not tell the full story about all platforms)

##🔄 Breaking Change AssessmentThis change removes`KeyConnectorUrl` from the root of the identity token response. Clients must read this value from`UserDecryptionOptions.KeyConnectorOption.KeyConnectorUrl` instead.**Client Compatibility:**- ✅ Web: Migrated in[version/commit]- ✅ Desktop: Migrated in[version/commit]- ✅ Browser: Migrated in[version/commit]- ⚠️ Mobile (iOS/Android):[Status/version info needed]- ✅ CLI: Migrated in[version/commit]All active client versions in production must support reading from the new location before this can be safely deployed.

Finding 2: Consider verifying all clients have migrated before merging

⚠️ Given the author's comment "Pausing b/c we should ensure mobile won't be affected negatively by this", this appears to be awaiting verification. Before merging, confirm:

1. All client platforms (Web, Desktop, Browser, Mobile iOS, Mobile Android, CLI) have deployed versions that read fromUserDecryptionOptions.KeyConnectorOption.KeyConnectorUrl
2. Minimum supported client versions are all updated (i.e., any legacy clients still in use that might break)
3. Rollback strategy is documented if issues arise post-deployment

The linked clients PR (bitwarden/clients#17593) should provide guidance, but mobile platform status needs explicit confirmation.

Code Quality Assessment

Security: ✅ No security concerns. This is a cleanup of deprecated functionality and doesn't change authentication/authorization logic.

Breaking Changes:⚠️ This IS a breaking change for any clients still readingKeyConnectorUrl from the root. Requires careful deployment coordination.

Test Coverage: ✅ Appropriate. The test inIdentityServerSsoTests.cs:524-526 that verified the backward-compatible root-level property was correctly removed, and the primary test for the proper location (KeyConnectorOption.KeyConnectorUrl) remains intact.

Code Maintainability: ✅ Good. The comment update inCustomTokenRequestValidator.cs:162-163 accurately reflects thatResetMasterPassword still needs cleanup, maintaining clear technical debt documentation.

Good Practices Observed:

• Clean removal of deprecated code path
• Updated inline comments to reflect current state
• Test assertions updated to match new behavior

Action Items

1. [REQUIRED] Confirm all mobile clients (iOS/Android) have migrated to readingKeyConnectorUrl fromUserDecryptionOptions.KeyConnectorOption
2. [RECOMMENDED] Document minimum client version requirements in the PR description
3. [RECOMMENDED] Coordinate deployment timing with client releases to ensure smooth rollout

Pausing b/c we should ensure mobile won't be affected negatively by this.
