You might want to look into ssh-agent Once this is set up properly you only need to enter your passphrase once at the start of a session. After that all authentication happens without prompting.
Another solution for automated scripts that I have seen used, but don't especially like, is null passphrases. If the server is configured to accept them you can create a key without a passphrase. ssh will not prompt you, or anyone, with this type of key.

Good luck brother,
