NAME

6       vncpasswd - change a VNC password

SYNOPSIS

9       vncpasswd [passwd-file]
10

DESCRIPTION

12       vncpasswd  allows  you to set the password used to access VNC desktops.
13       It stores an obfuscated version of  the  password  in  the  given  file
14       (default  $HOME/.vnc/passwd).   The vncserver script runs vncpasswd the
15       first time you start a VNC desktop, and invokes Xvnc with the appropri‐
16       ate  -rfbauth  option.   vncviewer can also be given a password file to
17       use via the -passwd option.
18
19       The password must be at least six characters long, and only  the  first
20       eight characters are significant.  Note that the stored password is not
21       encrypted securely - anyone who has access to this file  can  trivially
22       find  out  the plaintext password, so vncpasswd always sets appropriate
23       permissions (read and write only by the owner).  However, when  access‐
24       ing  a VNC desktop a challenge-response mechanism is used over the wire
25       making it hard for anyone to crack the password simply by  snooping  on
26       the network.
