Web Server User Settings
Here you can edit the user accounts that can access the web interface (if you disable public access).

Click on Add to create new accounts, use Edit and Delete to work with the accounts. You can also enter Comments for each user.
Make sure that each user is member of at least one group (by checking the boxes to the left of the group names) since you can only define the access on group level for sensors and panels.
