  1. Have the current Administrator log into the TSC.
  2. From the TSC Main Menu the current administrator will select Add/Update Users on the left toolbar, under Administrative Functions:
    • If the person who should be the TSC Administrator is listed as a user in the TSC, click on their User ID to access the account.
    • If the new Administrator is not a current user, select the +add user button and create a new User ID and temporary password for the person that should be the TSC Administrator. 
  3. While in the Add/Update User page the current administrator will need to be sure to check the box to assign the Administrator rights to this user as shown below.  The TSC Administrator is automatically granted full rights to file, pay, and view all activities for this account on the TSC.
