This is wrong.

The *right* way to do it is to generate a personal key-pair *with* a
passphrase and then read the manpages for ssh-agent and ssh-add. The
idea is that you start shh-agent <your shell> immediately after login.
Then run ssh-add, which will ask for your passphrase.

I use ssh that way all the time, type passphrase once and ssh to all
over the world, without typing passwords and without making all those
accounts vulnerable, even if my machine is hacked (unless my private key
could be read from the running ssh-agent, which I doubt).

Read those manpages, it might take a while to grasp the whole picture,
but it's worth it.
