You need to implement secure key authorization. Lots of help out there in google on how to do it. But the secure machine keys will authorize without a password.
A warning before you start the ssh-keygen will overwrite current key(s) in they exist. So making a backup might be a good thing. If you have some that are working they won't after the keygen....

maybe something like this page..
