User administation - account switching

When multiple dealerships are setup in Service Scheduler, users may be granted access to swap between sites without logging out and logging back in.

To enable, "Allow account change" must be checked in each account they are allowed to swap from. And the user must exist in all accounts with the same "username"

The passwords do not need to match, however in a local account setup it is recommended to avoid confusion if the user attempts to login to an account from the login dialog.
