📝 WalkthroughWalkthroughThe GitHub authentication extension now hydrates sessions directly from the active token and tracks Device Authentication session IDs through creation, cleanup, removal, and rollback. It clears tracked IDs when authentication becomes invalid or sessions are fully cleared. Copilot now shows a GitHub sign-in action when authentication fails and throws an error with a specific authentication-required message. Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🟡 Moderate · up to The PR invalidates persisted Device Authentication sessions, but unresolved failure modes can leave sessions untracked or survive delayed and concurrent updates, while hydration may fail without retry. This could preserve stale access or prevent expected reauthentication, so merge requires owner follow-up or explicit acceptance. Sequence Diagram(s)sequenceDiagram

pre-hydration sessions list is empty. Update the device-auth session tracking
around deviceAuthSessionStorageKey to include hydratedSessions and store the
resulting IDs before returning, while preserving existing session IDs.
- Around line 209-215: Update the persisted session-ID parsing in the GitHub
authentication provider to validate the JSON result at runtime, returning an
empty list unless it is an array whose elements are all strings. Keep the
existing warning and fallback behavior for parse failures, and ensure only
validated string arrays are returned from this path.

Works as expected and described. when deleting device authentication from one workspace and reload the others, all are now disconnected.

Hello @RomanNikitenko
Please let me know your finding, I won't merge until then
I meant:
- on your recording I see that after restarting the second workspace Copilot chat panel only displays an error - no even
Sign inbutton at the bottom - so - a user probably has no idea - what's the problem and what to do to get Copilot working
- I would expect - at least
Sign inbutton at the bottom or directly in the Chat panel when a user starts to type something
Apart of that - please answer/address review comments from the coderabbitai bot
I'm going to have a vacation during next 2 weeks - please feel free to the merge the PR when it looks good to your and other reviewers

Retry hydration after delayed service readiness.
If whenReady remains pending beyond the five-second timeout, hydrateFromK8sToken() can call getToken() before tokenInfo is set. getToken() then throws, and extension activation has no retry path. Defer or retry hydration after readiness, and add a delayed-readiness regression test.

Preserve the machine-readable GitHubLoginFailed reason.
contextKeys.contribution.ts reads e.message as reason before checking instanceof GitHubLoginFailedError. With this change, expected unauthenticated and BYOK failures no longer use the debug path, and activation telemetry records the user-facing message instead of GitHubLoginFailed. Keep the machine-readable reason separate from the display message, or update the consumer to classify GitHubLoginFailedError first.

What does this PR do?
Fixes GitHub Copilot Device Authentication sessions being restored by VS Code after the Device Authentication token has been removed.
The PR tracks authentication sessions created using Device Authentication in VS Code SecretStorage. During workspace restart, persisted Device Authentication sessions are removed when Device Authentication is no longer active.
The provider also avoids immediately recreating a session using a fallback PAT/git-credential token after removing the persisted Device Authentication session, requiring the user to authenticate again.
CRW-11730.mp4
What issues does this PR fix?
Fixes the issue where removing the GitHub Copilot Device Authentication token from one workspace does not invalidate the persisted authentication session in other existing workspaces.
After removing the Kubernetes
device-authentication-secret-*secret, another workspace could restore the previously persisted VS Code authentication session after restart and continue using GitHub Copilot without re-authentication.How to test this PR?
