Can end users manage their own connections?

Yes.

Yes. Pass show_disconnect: true in the /auth/generateWidgetSession request body alongside reference_id (it defaults to false).

Terra uses the reference_id to detect existing connections and shows a disconnect button for already-linked devices, instead of prompting Connect again. If your SDK's typed params don't include show_disconnect, send it via a direct API call or extend the params object.

As an API alternative:

• List a user's connected devices with the /subscriptions endpoint (keyed by reference_id).

• Disconnect with /auth/deauthenticateUser.

No custom UI is required if you use the widget option.
