For your SSH example, pubkey authentication has a bit of a learning to to set up but then makes ongoing use far easier.
For networked file systems, at work we have a common shared drive (H:) and a private shared drive (J:). The private drive is clearly more secure as people who shouldn't have access can't even see the files, but it's also much easier to use as you don't have to sort thru tons of other people's old crap.
