Config Admin & Config Accounts Admin - If you select the boxes for these near the top of the screen, this will give the user access to these at the merchant level. Only grant this level of access to someone who should have permission to make changes to all locations and queues. If the user should only be able to make these changes specific locations, grant access under the location permissions.
Note, if you are using Single Sign On, do not use the mass account creation tool as it does not allow you to set a username. Usernames for SSO setups need to be email addresses.
