NAME
       tigervncpasswd - change the VNC password


SYNOPSIS
       tigervncpasswd [passwd-file]
       tigervncpasswd -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
       $XDG_CONFIG_HOME/tigervnc/passwd  if  no  passwordfile  is  specified.)   The  tigervncserver script runs
       tigervncpasswd the first time you start a VNC desktop, and it  invokes  Xtigervnc  with  the  appropriate
       -rfbauth option.  xtigervncviewer 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 tigervncpasswd 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.

              A view-only password must be separated from the normal password by a newline character.


FILES
       $XDG_CONFIG_HOME/tigervnc/passwd
       $HOME/.config/tigervnc/passwd
              Default location of the VNC password file.

       participated in development, testing and support. This manual is part of the TigerVNC software suite.
