173173When `inferenceVertexOAuthClientId` and `inferenceVertexOAuthClientSecret` are both set, the app shows a **Sign in with Google** page at first launch. Clicking the button opens the system browser for a standard Google consent flow, and the app listens on a loopback address for the redirect. On success, the app stores the user's Google refresh token encrypted with the operating system's secure storage (Keychain on macOS, DPAPI on Windows) and returns to Cowork.

175At the start of each Cowork session, the app writes an `authorized_user` Application Default Credentials file (the same format produced by `gcloud auth application-default login`) into the session sandbox and points `GOOGLE_APPLICATION_CREDENTIALS` at it. The Google Cloud client library inside the sandbox handles access-token minting and refresh automatically.

177177If the stored refresh token is revoked or expires, the app shows a **Sign in again** prompt; clicking it reopens the Google consent flow in the browser. If you deploy a new OAuth client ID, the app clears the stored token and shows the sign-in page on next launch.
