User groups let you manage you users' view and edit permissions easily. Admins can quickly set up different user types by modifying the user groups that users belong to and the settings of those groups.
To view and modify existing user group settings, administrators can head to the settings menu in the bottom left hand corner.
Once you are in the Settings Menu, click the Permissions option:
Admins can then select "Groups" from the dropdown.
The first user added to the account is an administrator. This user will be automatically added to the built-in Administrators and All Users user groups. Subsequent users will be automatically added to All Users only. Due to these default groups and group settings, the first user will be an administrator and subsequent users will be write-access users.
To create an admin, an existing admin can add the user to the Administrators user group.
A user is a write-access user if they belong to at least one group that has edit permissions. This means that they belong to at least one user group that has the "Can Edit" column checked in the Group Settings.
By default, the All Users group has edit permissions, making all users write-access users. This can be modified as shown in the section below.
A user is a read-only user if they do not belong to any groups that have edit permissions. In order to create a read-only user, the All Users group must not have edit permissions. Hovering over the group will cause a Gear Icon to appear on the right.
Clicking the gear will make the "Can Edit" section editable for the group. Unchecking the box ensures that new users will be read-only.
