NAME
       tigervncpasswd - change the VNC password


SYNOPSIS
       vncpasswd [passwd-file]
       vncpasswd -f


DESCRIPTION
       tigervncpasswd  allows  you  to set the password used to access VNC desktops.  Its default behavior is to
       prompt for a VNC password and then store an obfuscated version of this password  to  passwd-file  (or  to
       $HOME/.vnc/passwd  if no password file is specified.)  The vncserver script runs vncpasswd the first time
       you start a VNC desktop, and it 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 (unless  the  -f  command-line  option  is  used--  see
       below),  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  plain-text  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.


OPTIONS
       -f     Filter  mode.   Read  a  plain-text  password from stdin and write an encrypted version to stdout.
              Note that in filter mode, short or even empty passwords will be silently accepted.


FILES
       $HOME/.vnc/passwd
              Default location of the VNC password file.

       VNC was originally developed by the RealVNC team while at  Olivetti  Research  Ltd  /  AT&T  Laboratories
       Cambridge.   TightVNC  additions  were  implemented by Constantin Kaplinsky. Many other people have since
       participated in development, testing and support. This manual is part of the TigerVNC software suite.
