Uplne jedno to zas nie je. Ja osobne pouzivam ssh. Treba vygenerovat
kluc na masine z ktorej sa hlasim, prekopirovat ho do
$HOME/.ssh/authorized_keys
a potom netreba zadavat ziadne heslo. Pozri manual k ssh. To hlavne z neho:

     ssh implements the RSA authentication protocol automatically.  The user
     creates his/her RSA key pair by running ssh-keygen(1).  This stores the
     private key in $HOME/.ssh/identity and the public key in
     $HOME/.ssh/identity.pub in the user's home directory.  The user should
     then copy the identity.pub to $HOME/.ssh/authorized_keys in his/her
home
     directory on the remote machine (the authorized_keys file corresponds
to
     the conventional $HOME/.rhosts file, and has one key per line, though
the
     lines can be very long).  After this, the user can log in without
giving
     the password.  RSA authentication is much more secure than rhosts
authen­
     tication.
