Bad idea. which "remote host" is that? That suggests that you are on the
net.

Anyway, I think what y ou really want is rsa identification. On your local
computer run
ssh-keygen -t rsa
and when it asks for the name take the default, and when it asks for
password just hit return.
(Yes, this can make it dangerous if someone breaks into your machine as you
or root. On the other hand they could then install a keyboard sniffer and
get the info anyway. The main concern is if unencrypted backups are made to tape, and
someone steals the tape.)
Then do
ssh user@remotehost echo `cat .ssh/id_rsa.pub` '>>.ssh/authorized_hosts'
(this means copy the full content of the file .ssh/id_rsa.pub on your local
machine to the end of the file .ssh/authorized_hosts in the directory of
user on the remote machine)
Now you will be able to log onto user@remotehost without a password

>Or is there any other trick which prevents me from being prompted for the password?

See above.
