How can I set a fixed custom password in Teamviewer (server) without sending registration data?

I use often TeamViewer both for Windows and Linux (sometimes even for other platforms, like Android) As long as ID does not change between Teamviewer reopenings, it would be useful to define a permanent password so I can connect remotely.
But the program seems to require some kind of registration, and I am a bit of a privacy fanatic.

Does anyone know how could I set a fixed (between reboots) password without registering?

P.S: The command:

teamviewer --passwd [PASSWD]

would be fantastic, but it does not work at all (tested on Ubuntu and Kali, and Windows seems not to have it as for today, on March 2014): the Teamviewer windows simply does not open. If someone knows how to make it work, please tell me, I would prefer it.

Teamviewer has to work through their central system in order to find the computer to control anyway--while there may not be an official registration they have to know. Why not just get a free e-mail account somewhere and use that to register? – Loren Pechtel – 2014-04-18T00:11:03.480

Mostly for faster configuring the TeamViewer server itself. Sometimes I want to do this on a network with dozens of computers, so I will gain some time. For the rest, you are right, @LorenPechtel, they could know much more than they are supposed to know. I think the future will confirm us details about our privacy with remote control programs that will scare us (Snowden showed us some examples, didn't he?). – Sopalajo de Arrierez – 2014-04-18T00:18:56.197

Follow these steps (tested with v9 and v10):

Press the pencil icon (below the password and ID assigned).
Press "Next".
Input your password (twice).
Press "Next".
On the next (registration) screen simply press "Cancel".

You will now see a hidden password beside the pencil. Your custom password is now stored and Teamviewer will always accept it, but (supposedly) you did not send any registration data.

Tested working on Linux and Windows. I suppose will work on most of the other operating systems.

The

teamviewer --passwd [PASSWD]

actually is normal that it doesn't show any window. It will just start the teamviewer daemon in the background waiting for connections (or if it is already started it will make it restart) since it's used to start the program over SSH and simillar where you don't necessarily have a display. Try checking with

ps ax | grep teamviewer

and you should see it's instance running after the command (or if it was already running you'll see it with a changed PID).

No, it does not. You are right: the daemon changes PID. But I can not connect; just like if there were no Teamviewer program (server) listening or opened. I have tested it on Ubuntu and Kali. I did open a thread on AskUbuntu (since it is more appropriate) here: http://askubuntu.com/questions/425494/teamviewer-not-starting-from-command-line-when-using-passwd-switch
