Chapter 7: Making Connections Secure
Specify and confirm a password, and click the OK button. Publish this password to prospective users, and in
addition notify that there is no need to enter a user name in the VNC Viewer Authentication Credentials
dialog, even if its Username field is enabled. More on this dialog.
Specifying additional passwords
If you choose to use VNC authentication as the mechanism for VNC Server (Enterprise) or VNC Server
(Personal), you can specify up to two additional passwords, enabling you to differentiate between basic,
standard, and power users.
Note: VNC Server (Free) does not support additional passwords. Upgrade the host computer to VNC Server
(Enterprise) or VNC Server (Personal) if flexibility is important to you.
Providing the Extended Configuration button is enabled, click it to open the VNC Server - Extended
Passwords dialog:
To give connecting users:
• The power to bypass connection prompts (if enabled), turn on Enable “Admin” user, and click the
adjacent Set password button to specify and confirm an admin password. Publish this password to
prospective users, and in addition instruct them to enter a user name of Admin. For more information on
connection prompts, see Preventing particular users connecting on page 113.
• View only access to the host computer, turn on Enable “ViewOnly” user and click the adjacent Set
password button to specify and confirm a view only password. Publish this password to prospective
users, and in addition instruct them to enter a user name of ViewOnly.
Relaxing the authentication rules
You can relax the authentication rules for all prospective users if you consider it safe to do so. For more
information on the default authentication mechanisms, see Authenticating connections to VNC Server on
page 98.
Note: Alternatively, you can allow particular users to bypass authentication altogether. For more
information, see Bypassing the authentication rules on page 107.
For VNC Server (Enterprise), you can relax the authentication rules so that users:
• Need only enter a VNC password. This forgoes the need to publish host computer user credentials, and
for users to have to remember a user name. For more information, see Authenticating using a VNC
password on page 103.
