When an agent signs in through the browser on your Mac, that login is automatically synced to your workspace's browser profile store.
This means the login becomes available in future chats — on the web or Mac — without the agent needing to sign in again. The sync happens in the background once the agent completes a browser sign-in.
Where: Mac app. Synced logins appear in Settings › Agents and apps › Browser logins.
Good to know: browser login sync is on for all workspaces and applies to Hermes, Claude Code, and Codex. Logins synced from Mac default to your workspace profile unless you move them to Private. Personal logins remain saved for you and are not used in team tasks. Related: Workspace vs private browser profiles, Manage saved browser logins.
