USER MANUAL
Managing Users, Groups and Shares
About Users
The Administrator, normally the device owner, is the person in charge of setting up the
device. As the WD My Cloud EX4 device owner, you have a special user account (admin)
that provides you with administrator privileges. With these privileges, you can set up and
configure the device to your specific needs and add other users to your personal cloud. You
also have the power to determine exactly what users can access on the device.
As a default, the administrator (admin) user name does not have a password. You can
create one at anytime (see “Updating a User Password” on page 41).
Note: Only one individual at a time can use the Administrator logon ID to log into the web
browser application. Because of this, ensure that you log out of the
WD My Cloud EX4 device web browser application when you’re not using it. This
allows other users authorized to use the Administrator logon ID to access the web
browser application. See Energy Saver - Web Access Timeout on page 115 to
automatically log out of the application after a set amount of time.
The Users screen displays a list of the current users and allows the Administrator to
view user details, create new users, create groups, and grant a user access to existing
shares.
