       tigervncpasswd - change the VNC password


       vncpasswd [passwd-file]
       vncpasswd -f


       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.


       -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


              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.
