[TYPO3] automatic FE logout after login

[Andreas Balzer]

Hi! Is it possible to log out a FE user via TSC at the end of a page?
I would like to create a login where a user has to insert an accesskey 
in order to create a new account for a community. I would like to verify 
the key, show some special contents and log the FE user out immediatly, 
so that the page is still shown and he does not have to click anywhere 
to do it..

Is this possible somehow?

Thanks for any help.
Andreas
