You may want to tweak the setup a bit, but that's easily done in a text
file or two.

Setting up public key auth is as simple as getting the users' public
keys onto the servers so they can log in, and verifying the correct
permissions. One public key per user you expect them to use.

Using passwords means the passwords are sent over the net using weak or
no encryption. Public keys themselves are not sent over the net.
Instead, one-off tokens are sent.

Also, once you have the public keys set up, the user can
ssh/scp/etc. onto the server without ever giving a password, which is
convenient. This allows automation, such as scripted backup at midnight.

Also, many programs now operate on top of ssh, and public key auth
means they don't require the user to enter a password. rsync, amanda,

I use public key auth on my home network out of laziness more than out
of security concerns.
