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 $HOME/.vnc/passwd if no password file 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

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