vncpasswd(1) -- Linux man page
NAME
vncpasswd - change a VNC password
SYNOPSIS
vncpasswd
[passwd-file]
DESCRIPTION
vncpasswd
allows you to set the password used to access VNC desktops. It stores an
obfuscated version of the password in the given file (default
$HOME/.vnc/passwd). The vncserver script runs vncpasswd the first
time you start a VNC desktop, and invokes Xvnc with the appropriate
-rfbauth option. vncviewer can also be given a password file to
use via the -passwd option.
The password must be at least six characters long, and only the first eight
characters are significant. Note that the stored password is not
encrypted securely - anyone who has access to this file can trivially find out
the plaintext password, so vncpasswd always sets appropriate permissions
(read and write only by the owner). However, when accessing a VNC desktop a
challenge-response mechanism is used over the wire making it hard for anyone to
crack the password simply by snooping on the network.
FILES
