As previously mentioned your key is not password protected unless you set a
password on it. Many companies have outlawed using ssh with RSA (or DSA in ssh
v2) keys for this very reason. Protect your keys with a password and use
ssh-agent. I wouldn't allow anyone to access my ssh server using an unprotected
key.
