ssh keys are required for what you want - do this to make keys:

I assume that you appended your keys to your ~/.ssh/authorized_keys file on the system you want to be able to ssh into.

Check file permissions on the following directories on this system.
     ~/.ssh directory
     ~/.ssh/authorized_keys file

The permissions should allow writing only by the ownwr, i.e. you.
