Another suggestion is to use a public/private key pair to login, and
disable password logins altogether. This prevents dictionary attacks
against the password. This also enables single-signon functionality, since
you can setup ssh-agent to store your decrypted private key in memory on
the client, and login multiple times without typing a password. Just
remember to protect the private key with a strong passphrase.

You put the public key in the .ssh/authorized_keys file on all SSH servers
you want to login to using the corresponding private key.
