Do Opera Workspaces retain tab groups after account credential expiry?

Goal

Determine whether the locally cached Workspace tab state in Opera remains accessible offline when the associated Opera account credential becomes invalid or the account is revoked.

Context & Constraints

Opera Workspaces is a documented feature that groups tabs locally and can sync via a single Opera account. The account login grants broad access to bookmarks, passwords, history, settings, and Workspaces, but no fine‑grained least‑privilege scopes are published. Current documentation does not describe the effect of credential expiry or revocation on local caches, and behavior may vary by OS, browser version, and whether the device is online.

Unresolved Questions

• What happens to the locally cached Workspace tab state when the Opera account credential expires or is revoked?
• Does the browser still allow offline access to the tab groups, or does it delete them upon credential expiry?
• If the account is signed out, does Opera prompt for re‑authentication before restoring the Workspace data, or does it keep the data until the next sync cycle?
