You can edit an Administrator's details by navigating to People > Administrators > select the Administrator > Edit Profile, before adjusting the Administrator's details and clicking Submit.
The Administrator's last name and 'Default Client View' are required fields, and we recommend that you include an email address so that the Administrator can receive important communications. You can also add in Custom Fields (and also make these required) which will appear under the 'Extra Fields' tab.

Note: The Permissions checkboxes only appear on this form if you hold 'Edit Branch Settings' or 'Edit Company Settings', and you cannot change your own permissions. For 'Owner', 'Change Branch', 'Edit Branch Settings', 'Edit Company Settings' and 'Use and configure the API', you can only grant a permission that you hold yourself. You can read more about Administrator Permissions here.
