tigervncpasswd - change the VNC password

       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.

TigerVNC                                                                                       tigervncpasswd(1)

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.

-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.
