It's really handy to have all my SSH authentication be passwordless, but in a secure way. In openSUSE, the
ssh-agent is started for you automatically, but you still need to add your identities manually (and enter passphrases when you do this). That's a bit of a pain to do every time you login.
Here are some simple scripts and steps I use to set up my KDE session so that it will automatically load my SSH identities when I login.
