Admin and Key User Accounts
Admin and Key User accounts in CentreWare IS enable you to limit access to specific printer functions
by specifying passwords for user classes. CentreWare IS requires a name and password before access to
the controlled printer functions is allowed.
The user classes are:
• Administrator: The person with the ultimate management responsibility and authority for
controlling some or all of the printer functions.
• Key User: A person who has some administrative responsibilities and who manages some or all of
the printer functions.
• Any User: Includes the majority of people who will be sending print jobs to the printer.
Once the passwords are set, select the printer functions from the Feature Authorization list that each
user class has the right to access. The three categories of printer functions are:
• Administrative
• Web Server Printing
• Printer Neighborhood

HTTP, HTTPS, and SSL/TLS
HTTP (Hyper Text Transfer Protocol) is used to communicate across the Internet between the printer
Web server and the Web browser (clients). Because the data is transmitted in plain text and passwords
are only slightly encrypted, it is not secure; the data can be read or intercepted by other people.
HTTPS (Secure Hyper Text Transfer Protocol) is a secure version of HTTP. HTTPS provides
authentication and encrypted communication to preserve the confidentiality of your data. Instead of
using plain text, HTTPS uses either the SSL (Secure Socket Layer) protocol or the TLS (Transport Layer
Security) protocol to encrypt data, thus ensuring reasonable protection from eavesdroppers and man-
in-the-middle attacks.
