How to change who can log-in to your websites
To change who is allowed to log in, use the "Change who may access this site" menu item:
Then enter the netid of the person you want to give access to the site and click Submit:
After clicking Submit the person's netid will appear in the list of netids with the Account Status set to "future", meaning they have not yet logged in.
Optionally, I can assign roles to future users. I trust "kakyle" who will be logging into the site shortly and co-managing the site with me, so I checked multiple roles. Generally, site editors for my site will have "content editor" permissions only and most faculty, staff, students who will want to update their profiles, will not have any roles selected, which means they have basic authentication rights.
