Do we need to have a password field in the config?

[bmorcos]

The fpga_config file has the password for the device written out in plain text. While this probably isn't a big deal in most cases (since it's the default user/pw on a local network) we might want to look into other ways of authentication?

Just putting this thought here so it isn't lost.

Hmm. Yeah, we could get the user to set up an ssh-key from the host PC, so that passwords are not necessary at all.

As mentioned by @xchoo, ssh removes password requirement but now we must decide on default behaviour (always use ssh? no need for password at all?)

Just as a point of clarification, it always uses SSH, it's whether or not to use the SSH keys for the SSH authentication process.
