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
