Again, before we go on, do you want to use ssh or do you want to use
rsync --daemon?  There are ways in both cases to do transfers without
a password, but the way you do it is very different so let us know which
one you want.  Your original question showed you seemed to be trying both.

With ssh, the easiest way is usually to do a ssh-keygen without a passphrase
and copy the public key into ~/.ssh/authorized_keys on the server.  With
rsync --daemon, the default is no password but if that's a security problem
you can use a "secrets file" on the server side and use the --password-file
option on the client where the file is not world readable.
