If what you are looking for is password free access to your machines via 
ssh (and friends), then you could simply set up a pair of keys for ssh 
on each machine.  There are many how to's on the internet, such as 
http://www.linuxproblem.org/art_9.html, 
http://www.thegeekstuff.com/2008/11/3-steps-to-perform-ssh-login-without-password-using-ssh-keygen-ssh-copy-id/, 
etc.

I do this often, as it allows other applications that use ssh (rsync, 
rdiff-backup) to be run from scripts.
