If you're the current account administrator and need to add or update administrator access for another user, follow the steps below:

1.Log In
Sign in to your account using the current administrator credentials.

2. Access the Administrator Settings
Click on your Welcome Menu, then select the "Administration" option from the dropdown.

3.Check for the User’s Email Address  If the email address of the new administrator is already listed:
Click the two arrows icon next to their email in the list to update their permissions and grant administrator access. 

If the email address is not listed: Click the “+ Invite New Member” button to send an invitation to join the account and select “Yes” to administrator level access for that new member before sending the invitation. Once the invited member accepts and joins the account they will then have access at an administrator level.

To remove an existing administrator, on the Administration section - click the two arrows icon again and remove their administrator status level access by selecting “No”. Then if needed the email address can also be disabled, which will remove them from the web account.  It’s recommended to assign a new administrator before removing the current one.
