       vncpasswd - change a VNC password


       vncpasswd [passwd-file]


       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.


              Default location of the VNC password file.
