WinZip to the rescue

I have web host clients I prefer to steer down the SSH route since it
reduces the likelihood of me getting "I've lost my password" emails.
I've found the Mac & Windows clients pretty decent and pain-free once
they're set up. Having iterated through this a few times i've ended up
with this page,
which even technically-challenged folks can follow now. Since it
involves them producing their own key it doesn't require any shared
secrets. The times I've run into troubles I've found SMS a good medium
for those.

HTH, Paul
